Fabrication of Amidoxime grafted Sepiolite into Chitosan based beads for pollutants removal

Currently I am working on bio-nanocomposite. Particularly on Chitosan based membranes and beads. My work is also based on the synthesis of nano-hybrids for environmental clean -up purpose. The nanohybrid we synthesized is based on Amidoxime modified sepiolite (clay). Our aim is to use this nanohybrid as filler in chitosan to improve its properties. Currently our group is focusing on the removal of textile dyes and heavy metals from industrial waste by using above mentioned nanohybrid in powder form and with the support of chitosan. In Pakistan we are facing environmental issues, most importantly, large amount of arsenic was found in our ground water. Initial results showed that this material have adsorptive tendency towards copper ions and some textile dyes (methylene blue).

I am also engaged in a group who has affiliation with French University (University Savoie Mont Blanc) under Pak-French program, we are working on chitosan based beads formation through periling technique for industrial purposes. In short my focus is on synthesizing environmentally eco-friendly bio-nanocomposites to replace petroleum based materials.
