Solochrome Black-T Removal From Aqueous Solution Using Activated Carbon Prepared From Bottle Guard Peel

Abstract

In the present investigation, activated carbon prepared by chemical activation method from bottle guard peel has been used for the removal of solochrome Black-T dye from aqueous solution. Batch adsorption studies were conducted to study the effect of contact time, adsorbent dosage and initial dye concentration on the adsorption. Data analysis was done by different adsorption isotherms such as Langmuir and Freundlich and  the results showed Langmuir isotherm as a suitable model to define the adsorption behaviour. Kinetic study was carried out using pseudo - first order, pseudo- second order models and  intraparticle diffusion rate and the pseudo-first order model described the solochrome black-T adsorption process with a well-fitting (R² = 0.9962).
