- Abstract
Proton exchange membranes (PEMs) were synthesized using three different compositions of poly(oxy ethylene) (POE), poly(vinyl alcohol) (PVA), chitosan (CS) and phosphoric acid (PA) in the weight ratio of 1:1:1:1, 1:2:1:1 and 1:3:1:1 by physical blending and casting method. Water uptake of the membrane increases with increase in the concentration of PVA. Higher percentage of water uptake signifies higher ion exchange capacity (IEC) of the synthesized membrane. Synthesized membranes were evaluated in microbial fuel cells (MFCs) and observed the performance. Synthesized membranes were characterized for identification of precursor material and inter polymer interactions using X-ray diffraction (XRD) and Fourier transforms infrared (FTIR) spectroscopy analysis respectively. Chemical oxygen demand (COD) removal (%) depends on microbial activity in anodic chamber. The present study was investigated to optimize the composition of the membrane and compared with other membranes which were synthesized by different compositions of all materials. COD removal (%) in MFC-3 setup connected with M-3 membrane was found to be 88%.
