Abstract

 Background: Nowadays, removal of heavy metals from the environment is an important problem due to their toxicity.Objectives: In this study, a modified method was used to synthesize CHITOSAN-coated MAGNETITE NANOPARTICLES (CCMN) to be used as a low cost and nontoxic adsorbent. CCMN was then employed to remove Hg2+ from water solutions.Materials and Methods: To remove the highest percentage of MERCURY ions, the Box-Behnken model of response surface methodology (RSM) was applied to simultaneously optimize all parameters affecting the adsorption process. Studied parameters of the process were pH (5-8), initial metal concentration (2-8 mg/L), and the amount of damped adsorbent (0.25-0.75 g). A second-order mathematical model was developed using regression analysis of experimental data obtained from 15 batch runs.Results: The optimal conditions predicted by the model were pH=5, initial concentration of MERCURY ions=6.2 mg/L, and the amount of damped adsorbent=0.67 g. Confirmatory testing was performed and the maximum percentage of Hg2+ removed was found to be 99.91%. Kinetic studies of the adsorption process specified the efficiency of the pseudo second-order kinetic model. The adsorption isotherm was well-fitted to both the Langmuir and Freundlich models.Conclusions: CCMN as an excellent adsorbent could remove the MERCURY ions from water solutions at low and moderate concentrations, which is the usual amount found in environment.
