Synthesized Nano particle derivation of poly (Styrene – co- Maleic Anhydride) and Sour Cherry Rock for removing Nickel (II) ion from aqueous solutions

In this study, Prunus Cerasus Rock (PCR) and Poly (Styrene – co- Maleic Anhydride) modified with Melamine-Oxalic acid (SMA-MO) were used to prepare a cheap adsorbent through chemical modification. The maximum removal was observed at pH = 6.0 and adsorbent dose 1.5 g/L for initial Nickel -ions concentration 30 mg/L. Study of temperature effect proved that the process is endothermic. Langmuir and Freundlich isotherm models were used for equilibrium adsorption data. Langmuir isotherm proved to be a better fit. Pseudo first order and pseudo second order kinetic models were applied to analyze the kinetic mechanism of adsorption.
