This study deals with the adsorption of Reactive blue 4 (RB-4) dyes onto puffed rice. Batch experiments were performed to evaluate the effects of various experimental parameters like pH, initial concentration, ionic strength and temperatures of dye solutions. The adsorption of RB-4 were found to be most favorable at pH 2, Adsorption of RB-4 followed pseudo-second order kinetics. Calculated activation energy value gives idea about some sort of chemisorption may involve in the adsorption. The value of thermo dynamic parameters shows the adsorption process is endothermic and spontaneous in nature, and three equilibrium isotherm models (Tempkin, Freundlich, Langmuir, isotherm models) were used to analyze the adsorption process. Out of these three models, Langmuir isotherm was found to be best with experimental data for adsorption of RB-4 onto puffed rice. The results indicate that puffed rice is a good adsorbent for the adsorption of RB-4 from wastewater and it is also reusable.
