Water pollution caused by heavy metal ions is becoming a serious threat to human and
aquatic lives day by day. Therefore, the treatment of heavy metal ions is of special concern …

The increasing water demand and the worldwide shortage of clean water call for new
technologies for wastewater treatment, of which adsorption is a simple and efficient method …

Chromate is considered to be a toxic contaminant because of its potential to harm animal
and human health. In this study, polypyrrole/calcium rectorite clay composites (PPy/Ca-REC …

This work successfully created a polypyrrole-polyethyleneimine (PPy-PEI) nano adsorbent
for the elimination of the lead ion Pb2+ from an aqueous solution. An efficient conducting …

The purpose of this study was to investigate the adsorption of uranium (VI) ions on the
polypyrrole adsorbent. Polypyrrole was synthesized by a chemical method using …

In order to use nitrogen atoms in polymers as the active adsorption sites for heavy metal
ions, an effort has been made to couple polyethyleneimine, a water soluble polymer with …

Glycine doped polypyrrole (PPy-gly) adsorbent was prepared via in situ polymerization of
pyrrole (Py) monomer in the presence of glycine (gly) for the removal of Cr (VI). Formation of …

Hexavalent chromium Cr (VI), one of the most toxic contaminants, is released in the
environment due to various anthropogenic activities. This study presents a novel …

This paper reports the synthesis of polypyrrole–titanium (IV) phosphate (PPy–TiP)
nanocomposite as a synthetic adsorbent for the adsorptive removal of Cr (VI) ions from …

The aim of this research work is to investigate sorption characteristic of acid treated brown
algae Sargassum bevanom (acid treated S. bevanom) for the removal of Cr (VI) ions from …
