Abstract
In this study, kiwifruit (kiwi) peel was used as adsorbent for the adsorption of dying reagents methylene blue and Rhodamine B. Effects of pH, starting dye concentration, temperature, and equilibrium contact time on the bio-sorption of methylene blue and Rhodamine B were investigated. Data were applied to Lagergren, Ho-Mckay, Weber -Morris kinetic models and the Langmuir and Freundlich adsorption isotherms. It was found that the adsorption isotherms follow the Langmuir model. However, the adsorption kinetics follow Ho-Mckay and Freundlich models for methylene blue and Rhodamine B, respectively. The isotherm data obtained at different temperatures for biosorption of methylene blue and Rhodamine B were applied to thermodynamics equations and thermodynamic parameters (Delta G, Delta H, and Delta S).
