In the present work the efficiency of activated carbon made from stems of Ricinus communis (CRC) has been studied for removal of anionic dye- Amido black 10B from aqueous solution. The adsorbent has been characterized with scanning electron microscopy (SEM) and Fourier transformer infrared (FT-IR). The effects of various experimental parameters such as contact time, adsorbent dose, initial dye concentrations, pH, concentration of salt and temperature have been studied. Langmuir, Freundlich and Tempkin isotherm models have been used for describing the adsorption process. Of these, Langmuir isotherm model has best fitted the experimental data with a maximum adsorption capacity of 7.12 mg/g. Kinetics studies indicate that the adsorption of Amido black 10B has favoured toward pseudo-second-order model with high correlation coefficients. Thermodynamics parameters confirmed that the adsorption has been found to be spontaneous and endothermic in nature. These results suggested that CRC has a potential low-cost adsorbent for the removal of toxic dye Amido black 10B.
