EFFECT OF DIFFERENT REACTION PARAMETERS ON REMOVAL OF MALACHITE GREEN BY ADSORPTION ON PUMPKIN PEELS

Abstract

In this work, pumpkin peels (PP), an agricultural solid waste, is proposed as a novel material for the removal of Malachite Green (MG) from aqueous solutions. The studies were carried out under various experimental conditions such as stirring speed, ionic strength and temperature of solution to assess the potentiality Pumpkin Peels for the removal of malachite green dye from wastewater. The results show that increasing in stirring speed leads to an increase in adsorption capacity at equilibrium. The best amount adsorbed at equilibrium was obtained at stirring speed of 300 rpm. The adsorption of MG is favored by high temperatures. The ionic strength disadvantages the adsorption of the dye...
