Nanoconducting polymer: An effective adsorbent for dyes

The nanostructured sulfonated polypyrrole adsorbents have been prepared by copolymerization of pyrrole and sulfophenylenediamine to study the adsorption efficiency of the polymer-based nano-adsorbents for the adsorption of anionic and cationic dyes in aqueous solution. The present study reveals that...
