摘要: Abstract In this study, the biosorption characteristics of crystal violet (CV) from aqueous solution onto treated ginger waste (TGW) were examined. The parameters studied effect initial dye concentration, contact time, pH and temperature. kinetic data obtained at different concentrations analyzed using pseudo-first order, pseudo-second order intra-particle diffusion models. experimental fitted to Langmuir Freundlich isotherms. maximum monolayer capacity was found be 64.93, 227.27 277.7 mg/g 30, 40 50 °C, respectively. Thermodynamic evaluated positive value ∆H0 indicated endothermic nature biosorption. breakthrough 72.6 mg for 0.3 g TGW. Attempts also made regenerate TGW acetic acid as eluent.
