Abstract
The feasibility of doing away with Acid Orange II dye from aqueous solutions the usage of adsorbent Activated Carbon of waste leather (ACWL) has been analysed. Batch mode adsorption researches are carried out in order to inspect the adsorption capacities of this adsorbent by using various initial dye concentration, contact time, temperature and pH. Results expose that adsorption capability decreases from 95.07% to 76.04% for (ACWL) at 30 ðC with an expand in the initial concentration from 10 to 60 mgl-1. The calculated qe values agree very properly with experimental values. The regression coefficient values above 0.99 verify that adsorption follows 2nd order kinetics. The enlarge in Langmuir adsorption potential (q0) is 17.66784 mgl-1 (ACWL) on growing the temperature from 30 to 60ðC bills for the endothermic nature of the process. The current study confirms the potentiality of plentiful low price solid waste leather and its availability for the elimination of acidic dyes from aqueous solution.
