However, to incorporate nanoparticles in membrane pores, monomer and cross-linker concentration plays a significant role during polymerization process. A change in monomer and cross-linker concentration could have effect the whole functionalization of membranes. So far there is no study regarding the effect of changing of monomer and cross-linker concentration on functionalized membranes.
For this study we have changed the monomer concentration from 10 to 20 wt% of polymer solution and cross-linker concentration from 0.5 to 1 mol% of monomer concentration during preparation of different batches of functionalized pH responsive membranes, keeping all other parameters constant. This give us a matrix of monomer and cross-linker concentration to do functionalization of membranes. The synthesized nanoparticles incorporated membranes were characterized by electronic microscopy, X-ray spectrometry and image analysis before-, after- nano particle loading.
Finally, we report the optimum concentration of monomer, cross-linker concentration along with Fe/Pd nano particle loading for making pH responsive membrane. These membranes have both responsive behavior and catalytic properties to degrade toxic organics (such as, TCE, PCBs) from water. We like to thank NIH-NIEHS-SRC for funding this research project.
