The goal of this study is to determine the ability of activated carbon derived from waste leather from theleather industry to adsorbed bisphenol-A, an endocrine disruptor, from aqueous solution. The functionalizedactivated carbon was found to have the best adsorption capacity at acidic pH. The weak vander Waals forceof attraction between the activated carbon’s surface and bisphenol-A The kinetics of adsorption were foundto fit well with a pseudo second-order reaction. Langmuir, freundlich, DKR, and the Elovich models wereused to correlate equilibrium isothermal data. Adsorption was observed, and there were no remarkablechanges after three hours. The effect of particle size revealed that the smallest one adsorbsmore due to theavailability of a large number of surface areas. The minimum initial concentration of theadsorbate favouredhigh adsorption. The process was endothermic, feasible, and spontaneous. Nearly 90% of adsorptions in anacidic medium were found. Overall, it was found that the activated carbon derived from waste leathercould be a new sustainable chemical technology for water purification.

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 °C 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 60°C 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.
