Mining, electroplating, tanning, and other industries produce wastewater containing high concentrations of toxic hexavalent chromium, Cr(VI). The release of Cr(VI) into water sources is a serious concern due to its high toxicity to humans and other organisms and high mobility in the environment. Therefore, industrial wastewater must be treated prior to reuse or discharge into the environment to ensure Cr(VI) levels are well below the maximum allowable limits prescribed by water quality standards. Conducting polymers such as polypyrrole (PPy) have been widely studied as adsorbents for Cr(VI) removal from water due to their ion-exchange properties and inherent ability to reduce Cr(VI) to less toxic Cr(III). However, conducting polymers have shown low adsorption capacities for Cr(VI) due to particle agglomeration and have other limitations. In this study, polypyrrole was modified by incorporating suitable dopants or other monomers into its structure in order to obtain adsorbents effective for the treatment of wastewater containing Cr(VI). Polypyrrole/2,5-diaminobenzenesulfonic acid (PPy/DABSA) composite and polypyrrole-m-phenylenediamine (PPy-mPD) polymer, were synthesized by in situ oxidative polymerization methods. The composites were characterized by using various techniques including FTIR, SEM, TEM, TGA, XRD, XPS and BET surface area analysis. Batch adsorption studies were carried out to evaluate the performance of the modified conducting polymers for the removal of Cr(VI) from aqueous solution. The PPy/DABSA composite and PPy-mPD polymer both showed high Cr(VI) adsorption capacities. Both composites selectively removed Cr(VI) from aqueous solution. The PPy/DABSA composite could be used for up to 3 cycles without any loss of adsorption capacity while the removal efficiency of PPy-mPD composite was found to decrease after each cycle. Modified conducting polymers were shown to be promising adsorbents for the remediation of industrial wastewater containing Cr(VI).
