Adsorption Studies of Methyl Tert-butyl Ether from Environment

The widespread use of methyl tert-butyl ether (MTBE) as a gasoline oxygenate additive has resulted in the presence of MTBE in the environment. This compound is considered as one of the main components of water pollution. Adsorption has received a lot of attention for the removal of MTBE from water. This review paper summarizes the results of adsorption feasibility of different adsorbent for the elimination of MTBE from aqueous solutions. It also discusses the major research topics related to MTBE removal by widely used adsorbents namely, granular activated carbon, minerals, resins and composites. Better understanding of these adsorbents and their affinity toward MTBE adsorption can help future research to be properly oriented to address knowledge gaps in this area. This review provides an opportunity for researchers to explore the removal functionality of MTBE by adsorption methods, better.

Influence of surfactants on Fe2O3 nanostructure photoanode

Fe2O3 nanostructures photoanodes were prepared via sol-gel spin-coating method onto fluorine-doped tin oxide glass substrates using six different surfactants: polyethylene glycol (PEG-300), Triton X-100, pluronic F127, cetyltrimethylammonium bromide (CTAB), octadecyltrimethylammonium bromide (OTAB) and tetradecyltrimethylammonium bromide (TTAB). The resulting films have thickness from 520 ¡À 10 to 980 ¡À 10 nm after calcinations at 450C in the air. A comparative study of photocatalytic activity of thin films was performed. The photo-generated samples were determined by measuring the currents and voltages under illumination of UV-vis light. The highest photocurrent density of 1.77 mA/cm2 at 1 V/SCE, under illumination intensity of 100 mW cm-2 from a solar simulator with a global AM 1.5 filter, were produced by TTAB treated sample. The optical properties, morphology, surface roughness and structure of the films were also characterized by UV-visible spectroscopy, SEM, AFM and XRD. The results are consistent with photocatalytic performance: TTAB treated sample has the highest grain size and optical absorption. The improved performance of this sample can be attributed to the crystallinity process of TTAB, which leads to the larger grain size and highest photocatalytic activity. The study demonstrates that photoelectrochemical performance of metal oxide can be improved by simply changing surfactant. The results highlighted the superior performance of cationic surfactants over non-ionic surfactants in preparing Fe 2O3 photoanodes by sol-gel method. Moreover, the study showed that decreasing hydrocarbon tail of cationic surfactants can increase the crystallite size and improve photocatalytic activity. Copyright

Toxicity of organoclays to microbial processes and earthworm survival in soils

Organoclays have wide spread application in environmental remediation and nanocomposites synthesis. Some of the quaternary ammonium compounds (QACs) commonly used to prepare organoclays are toxic to biota. However, information on the toxicity of organoclays is rarely available in the literature. This study assessed the toxicity of three laboratory prepared bentonite organoclays on the soil microbially mediated processes (such as dehydrogenase activity and potential nitrification) and soil inhabiting animals, such as earthworms. Toxicity to both microbial processes and earthworm followed the order: hexadecyltrimethyl ammonium modified bentonite. >. octadecyltrimethyl ammonium modified bentonite. >. arquad modified bentonite. >. unmodified bentonite. The organoclays were able to cause slight improvement (up to 25%) in the potential nitrification in some soils when they were added at low application rates up to 5%, but caused reduction (3-86%) in the dehydrogenase activity in all the soils irrespective of loading rates. The organoclays were extremely toxic to the survival and vigour of the earthworms. The average body weight loss of the worms reached as high as 62% in hexadecyltrimethyl ammonium modified bentonite treated soil even at 1% loading. This study holds utmost importance in assessing the toxicity of organoclays to soil microbially mediated processes and earthworms.

Spherical micelle formation by mixed quaternary ammonium surfactants with long, and short, tails in ethanol/water solvent and micellar freezing upon solubilising styrene polymerisation

The association of mixed docosyltrimethylammobium bromide and octadecyltrimethylammonium bromide, C22TABr/C18TABr, in ethanol (a common solvent favoured for both their alkyl tails and head-groups) induced by the addition of water (a non-solvent for the tails) has been studied using light-scattering measurements. Under the assistance of NaBr, which promoted the surfactant molecules to pack tightly in the micelles, mono-disperse spherical micelles composed of mixed C22TABr/C18TABr were obtained in ethanol/water (15/85?wt%). Styrene was solubilised into the templating C22TABr/C18TABr micelles (betasurf, the molar ratio of C18TABr to C22TABr, was 2.5) and then was polymerised in situ. To achieve a good freezing effect, the amount of styrene solubilised, represented as the molar ratio of styrene monomer to total surfactants, nst/nsurf, was required to be greater than 4.87 for this templating micellar system. The diluting tests demonstrated that, after polymerisation, the styrene-containing micelles froze their microstructure well. Light-scattering measurements, and TEM observation, all indicated that these micelles were mono-dispersed, and retained their spherical shape. As swollen by polystyrene, the micelle had an avarage radius of 18?nm.

Oxidative desulfurization of fuels at room temperature using ordered meso/macroporous H3PW12O40/SiO2 catalyst with high specific surface areas

Ordered meso/macroporous H3PW12O40/SiO2 nanocomposites with high specific surface areas were prepared using cationic surfactant and monodispersed polystyrene spheres (PS) as dual-template. The characterization results of scanning electron microscopy (SEM), transmission electron microscopy (TEM), N2 adsorption-desorption, and small-angle XRD patterns confirmed the existence of ordered meso/macroporous structure and the wide-angle XRD patterns, Fourier transform infrared spectroscopy (FTIR), X-ray photoemission spectroscopy (XPS) measurements suggested the high dispersivity of the Keggin-type heteropolyacid (HPA) on silica matrix. There was an optimum value of cationic surfactant usage and proper calcination temperature of ordered meso/macroporous H3PW12O40/SiO2 catalyst leading to ultra-high specific surface areas. Furthermore, the ordered meso/macroporous H3PW12O40/SiO2 catalyst was evaluated for ultra-deep oxidative desulfurization (ODS) of cyclic sulphur-containing compounds using hydrogen peroxide (H2O2) as oxidant. Under optimum reaction conditions, dibenzothiophene (DBT) could be removed within 100 min at 30 C by meso/macroporous H3PW12O40/SiO2 catalyst. The excellent catalytic activity should be attributed to the combination of ordered meso/macroporous architecture and high surface area of H3PW12O40/SiO2 catalyst which promoted the mass transport of reactants and products in the pore channel and provided more accessible catalytic active sites. In addition, the meso/macroporous H3PW12O40/SiO2 catalyst showed good stability with only 1.9% efficiency decreased after 6 cycles.

Formula optimization and rheology study of clean fracturing fluid

Clean fracturing fluid is a kind of environmentally friendly and non-polluting fracturing fluid. In order to obtain the clean fracturing fluid formula with low-dose surfactant and study the rheological properties of clean fracturing fluid, an indoor experiment was carried out. Firstly, through the optimization experiments, the main agent and the main agent concentration were determined. Based on the analysis of the effects of different inorganic and organic micelle promoters on the main agent by experiments, the type of additive and additive concentration were determined, and ultimately formed the clean fracturing fluid formula. Secondly, by means of viscometer and rheometer, the fluid type of the clean fracturing fluid was discussed, and the effects of temperature, inorganic salts, organic matter, as well as the pH value were also investigated. The experimental results indicate that the preferred clean fracturing fluid belongs to pseudoplastic fluid; temperature, inorganic salts and organic matter have significant effect on the system, and the pH value has little effect. Finally, with the help of Cryo-TEM, the microstructure of the clean fracturing fluid was verified. And the Cryo-TEM images show that the clean fracturing fluid system consists of a large number of winding wormlike structures, which is consistent with the rheological results.
