The effects of its concentration, adsorbent dosage, particle size, pH and temperature on removal of Ni（II） ion have been studied. The removal of Ni（II） ion is higher at lower concentration and gradually decreases as the concentration increases. The pH of 5 was the most suitable. The removal of Ni（II） ion increases with the increases in the adsorbent dosage. The effect of particle size reveals that the percentage removal of Ni（II） ion decreases with increase in particle size of adsorbent. The effect of temperature shows that as temperature increases, the percentage removal of Ni（II） ion decreases and this is due to the interaction forces weakening at high temperature. Thermodynamic parameters from the effect of temperature were calculated.展开更多
