Development of PVA/MIDA based hybrid cation exchange membranes for alkali recovery via Diffusion Dialysis
We report poly vinyl alcohol (PVA) based hybrid membranes composed of methyl iminodiacetic acid (MIDA) and tetraorthoethoxysilane (TEOS) prepared by classical sol-gel process. MIDA was prepared via N-methylation of iminodiacetic acid and then successfully incorporated into the PVA backbone. The concentration of MIDA with respect to PVA was varied from 10 to 40 wt%. These hybrid membranes showed water uptake (WU) in the range of 106-125%, ion exchange capacities (IECs) of 1.14-2.13 mmol/g, dialysis coefficient (UOH) from 0.009 to 0.012 m/h as well as selectivity (S) from 16.0 to 19.9. These obtained results revealed that MIDA. It controls the hydrophilicity and ion exchange capacity by providing channels for the transportation of ions through carboxylate sites. PVA/MIDA hybrid membranes also showed good thermal stability with the initial thermal decomposition temperature (IDT) ranging around 150-160 C and excellent mechanical properties such as tensile strength (TS) of 9-25 MPa and elongation at break (Eb) of 32-150%.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.name: 2,2′-(Methylazanediyl)diacetic acid, you can also check out more blogs about4408-64-4
