Batch adsorption experiments were conducted for the adsorption of Cd (II) ions from aqueous solution by activated carbon prepared from Lapsi seed stone. The activated carbon was characterized by Iodine number, Methylene blue number, SEM and FTIR. Adsorption experiments were carried out to describe the effect of pH ,contact time and  adsorbent dose on the metal ion removal process .The results showed that the adsorption of Cd (II) ions was very fast initially and the equilibrium time was 3 hrs.The pH of 6.0 was an optimal pH for adsorption  of Cd(II) ions. Langmuir and Freundlich adsorption isotherms were used to explain the equilibrium data. Langmuir model best described the data with higher value of coeffcient of determination as −1 compared to that of Freundlich isotherm showing a maximum uptake of 37.0 mgg . This study demonstrated that the activated carbons prepared from Lapsi seed stone could be used for the removal of Cd (II) ions in water treatment. Journal of the Institute of Engineering, 2015, 11(1): 140-150

This study compared the performance of cement kiln dust (CKD) as industrial byproduct and commercially activated carbon (AC) as adsorbent derived from agricultural waste for the removal of cadmium (Cd2+) from aqueous solutions. CKD and AC were characterized by Fourier transform infrared (FTIR) and scanning electron microscopy (SEM) and surface areas demonstrate the differences of physicochemical properties. Batch equilibrium experiments were conducted for various intervals extended to 96 h at 20, 25 and 30°C to investigate the efficiency of the sorbents in the removal of Cd2+. CKD expressed high affinity for removal of Cd2+ and was not affected by temperature, while AC was significantly affected, which reflects dissimilarity in the retention mechanisms defendant in CKD and those pursued by AC. The results were explained by changes of FTIR and SEM images before and after sorption experiments. The suggestion is that electrostatic ion exchange and complex reactions are the main mechanisms for Cd2+ removal. The kinetic data were evaluated by fractional power, Elovich, pseudo-first order and pseudo-second-order kinetic models. The pseudo-second-order kinetic model was found to correlate with the experimental data well. These results revealed that CKD can be used as a cost-effective and efficient sorbent for Cd2+ removal in comparison with AC.

The performance removal of chromium (VI) from polluted water is discussed in this paper. The sorption characteristic of Nitric Acid activated carbon derived from Vincarosea Apocynaceae plants through oxidation process and was proposed for the removal of Cr (VI) from polluted solutions. The surface chemistry characteristics of the prepared adsorbent were analysis by XRD, FTIR and SEM-EDAX. The effects are determined for removal of chromium they are initial concentration, PH level and adsorbent dose. The metal ion removal was pH dependent and, to a lesser extent, ionic strength. Kinetics data were found to follow the pseudo-second order kinetic model. Activation thermodynamic parameters, such as activation enthalpy (ΔH*), activation entropy (ΔS*), activation Gibbs free energy (ΔG*) and activation energy(E), have been evaluated and the possible adsorption mechanism also was suggested.
