Polymer-based adsorbent for heavy metals removal from aqueous solution

Verified

Habibun Nabi Muhammad Ekramul Mahmud, A. K. Obidul Huq, Rosiyah Yahya

Journal: IOP Conference Series Materials Science and EngineeringYear: 2017Citations: 22

A novel conducting polymer-based adsorbent, polypyrrole (PPy) fine powder has successfully been prepared as a new adsorbent and utilized in the adsorption of heavy metal ions like arsenic, zinc and cadmium ions from aqueous solution. PPy was chemically synthesized by using FeCl3.6H2O as an oxidant. ...
