Preparation and optimization of polyaniline /titanium dioxide /carboxymethyl cellulose powder for effective nickel adsorption

Hexanoic acid-doped polyaniline (PAni) is a great potential candidate to replace conventional adsorbent towards the removal of heavy metal waste from electroplating industry, especially nickel (Ni). In this study, different weight % (wt %) of titanium dioxide (TiO2 ) and carboxymethyl cellulose (CMC...
