Ginger waste material (GWM) has been utilized as adsorbent for removal of hazardous Patent Blue VF (PBVF) dye from aqueous solution. Batch adsorption experiments were performed as a function of pH, contact time, dye concentration, adsorbent dose and temperature. The optimum pH required for the maximum adsorption was found to be 2. The experimental equilibrium adsorption data were tested using Langmuir and Freundlich isotherm equations and maximum monolayer adsorption capacity was found to be 9.56 mg/g. Adsorption kinetics data were modeled using the pseudo first order and pseudo second order kinetic equations and intraparticle diffusion model. Results indicate that pseudo second order model best describe adsorption kinetics data.
