POLYPYRROLE NANO COMPOSITE AN EFFICIENT AND NOVEL ADSORBENT FOR THE REMOVAL OF DISPERSE RED 9 FROM TEXTILE WASTEWATER

S. SUPRIYA1 AND P.N. PALANISAMY

Abstract

In this research work, application of Polypyrrole coated onto wood saw dust (PPC) was employed for the removal of Disperse Red 9 (DR) from aqueous solutions. The effects of important parameters such as pH, initial concentration, adsorbent dosage and contact time on the uptake of DR solution were investigated by batch adsorption system. Surface morphology of adsorbent is studied through scanning electron microscopy. The effect of pH, initial dye concentration, adsorbent dosage and contact time has been studied at optimum experimental conditions. Results reveal that as the amount of adsorbent increases, the percentage removal of the dye also increased. The adsorption of DR dye onto PPC follows pseudo second order kinetics. Study on the dye by the adsorbent fits Freundlich and Langmuir isotherms well. The present study confirms the potentiality of an abundant low cost adsorbent and its availability for the removal of dyes from aqueous solution.
