Removal Of Safranin –O From Aqueous Solution By Adsorption Onto Carbonized Spent Coffee Ground

Dyes or colored compounds are the most effortlessly identifiable pollutants in the environment. Maximum of the industries use dyes and pigments to color their products. In the present study, carbonized spent coffee ground had been converted into a low cost adsorbent and characterized for SEM and FTIR. Batch adsorption studies are carried out by observing effect of amount of adsorbent dose, contact time, pH, and initial concentration of safranin-O on the adsorption capacity of the adsorbent were studied. The adsorption of safranin - O over carbonized coffee spent ground obeyed second order kinetics. It was found that the adsorption followed the Langmuir isotherm
