Abstract

Dyes are carcinogenic and toxic chemicals that affect aquatic life and human beings even at lower concentrations. Treatment of industrial effluents containing dyestuffs is therefore important for wastewater treatment engineers. In this study, batch adsorption experiments were conducted to study the adsorption of Reactive Blue 25 dye from aqueous solution using agricultural solid waste e.g., Bengal gram seed husk. The operating parameters are initial solution pH, initial dye concentration, adsorbent dosage and adsorbent-adsorbate contact time affecting dye adsorption were investigated. Experimental data were fitted to Langmuir and Freundlich isotherm models. Lagergren’s kinetic models were used to explain the adsorption kinetics and predict the theoretical adsorption capacity of adsorbent.
