【Abstract】 The immobilization of apatite on Cd 2+ was reviewed. The controlling factors to the immobilization, such as the crystal-chemical properties of apatite, pH, temperature, the amount of sample, action time and the impurity ion content in the solution was discussed. The mechanism for the immobilization including adsorption, dissolution-precipitation, surface-complexation was commented.更多还原
