摘要: AbstractThe aim of this study is to establish an economical and environment friendly method for the removal reactive dye from wastewater. This was carried out Drimarine Blue HF-RL using raw, nitric acid treated, immobilized peanut hulls in both batch column modes. In study, different process parameters like pH, biosorbent dose, initial concentration, contact time, temperature were optimized. The pH (2), dose (0.05 g), concentration (400, 200, 200 mg/L), time (90, 120, 120 min), (30°C) optimized hulls. biosorption data have been analyzed Langmuir, Freundlich, Temkin, Doubinin–Radushkevich, Harkins–Jura isotherms. isothermal followed Langmuir model. processes conformed pseudo-second-order rate kinetics. Different thermodynamic estimated during study. results showed exo...
