| Abstract | The removal of nickel from aqueous solutions was investigated using water washed raw leaves of Ricinus communis (RLRC). The adsorbent was characterized by Fourier Transform infrared spectroscope (FTIR), X-ray diffraction (XRD), scanning electron microscope (SEM) with an EDAX (energy dispersive analysis of X-ray), and zeta potential measurements will be carried out in order to find the iso electric point of the RLRC adsorbent. The effects of the presence of one metal ion on the adsorption of the other metal ion were investigated. The experimental results indicated that the uptake capacity of one metal ion was reduced by the presence of the other metal ion. The main focus of the work will be to recover, adsorbed the used adsorbent contaminant and regenerate the adsorbent for its reusing is of great importance for environmental and economical reasons.ie, RLRC will be recovered by desorption method by using proper desorption agent like H2O by batch mode study. The maximum adsorption of nickel was observed at pH 6 (56.32%). The Langmuir, Freundlich, Temkin and Dubin-Radushkevich isotherm models were used to analyze the equilibrium data. The data were also fitted to kinetic models such as pseudo-first order, pseudo-second order, Intra particle and Elovich model. The adsorption equilibrium data were well fitted by the Langmuir model. Kinetic studies showed that the adsorption followed pseudo-second order model and intra particle diffusion also. According to the experimental results, the adsorbent derived from this |
