Abstract

The adsorption capacity of bio adsorbent, prepared from Hyptissuaveolens (VilaytiTulsi), for Rhodamine 6G removal from aqueous solution was investigated in the present study. The effect of ph, initial dye concentration, time, adsorbent dosage and temperature was investigated. The present adsorption follows pseudo second order kinetics. Langmuir isotherm and Freundlich isotherm was used for present study. The maximum adsorption capacity under optimum condition was found to be 48.78 mg g-1. The thermodynamics study shows endothermic, spontaneous adsorption process.
