Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. , Formula: C21H38ClN, 139-07-1, Name is N-Benzyl-N,N-dimethyldodecan-1-aminium chloride, molecular formula is C21H38ClN, belongs to catalyst-ligand compound. In a document, author is Bisiriyu, Ibraheem Olayiwola, introduce the new discover.
Adsorption of Cu(II) ions from aqueous solution using pyridine-2,6-dicarboxylic acid crosslinked chitosan as a green biopolymer adsorbent
In this study, crosslinked chitosan (CCS) has been synthesized by anchoring a bifunctional ligand, namely pyridine-2,6-dicarboxylic acid (PDC) with chitosan through ion exchange. The functionalized biopolymer has been characterized using different instrumental analyses including elemental (CHN), spectroscopic (UV-visible, NMR, powder XRD, and FTIR), thermal analyses (TGA and DSC), surface and morphological (BET and SEM) analyses. The PDC-CCS was utilized for the recovery of Cu(II) fromwater contaminatedwith Cu. The adsorption limit/ capacity of PDC-CCS has been examined for solution pH, temperature, Cu(II) ion concentration, and the contact time of the adsorbent. An extreme adsorption limit of 2186 mmol.g(-1) has been found for the PDC-CCS. Equilibrium was quickly attainedwithin 60 min fromthe start of adsorption. Also, itwas discovered that the adsorption limit/capacity exceedingly relies upon temperature and pH. On testing the experimental data with the two most popular adsorption models (fundamentally, Freundlich and Langmuir), we found that Cu(II) ion adsorption suit both models. Similarly, the experimental adsorption kinetics is in reality, second-order. Thermodynamic studies also revealed that the adsorption processwas spontaneous and enthalpy driven. DFT calculations suggest that the main adsorption mechanism is by chelation through charge transfer from the adsorbent to the Cu(II) ions in solution. (C) 2020 Elsevier B.V. All rights reserved.
