Description
Summary:In this work we describe the utilization of a low cost environmental biomass derived from Ajuga Pseudo‐Iva waste (AP‐Iva) for the purpose of dye removal from contaminated wastewater. The biosorbent was characterized by SEM, ATG‐DSC, and FTIR‐ATR techniques. The material's performance was studied by varying operating parameters such as initial dye concentration, pH, adsorbent dose, particle size, and contact time. The results obtained showed that MV dye was sorbed quickly enough for the first few minutes and achieved a good efficiency (∼80 %) after 30 min of reaction time. The kinetic data obtained at different concentrations were analyzed using pseudo‐first order, pseudo‐second order, Elovich, and intra‐particle diffusion models. The equilibrium sorption data were analyzed using Freundlich, Langmuir, Toth, Sips, and Temkin isotherms. The experimental data were correctly fitted to Toth and Sips isotherms.
