Zinc is one of the most important pollutants for surface and ground water. Because of its acute Toxicity and non-biodegradability, zinc-containing liquid and solid wastes are considered as hazardous wastes. The aim of this research work is to investigate sorption characteristic of polypyrrole coated on the sawdust (PPy/SD) for the removal of Zn (II) ions from aqueous solutions. The sorption of Zn...
This paper deals with a new application of polyaniline (PAn) and polypyrrole (PPy) synthesized chemically. Coated on sawdust via cast method the polypyrrole/sawdust (PPy/SD) and polyaniline/sawdust (PAn/SD) were used as effective adsorbents for the removal of heavy metals, anions, color and COD (chemical oxygen demand) from mill paper wastewater. The products were investigated in terms of morphology...
