Removal of Cadmium Ions from Aqueous Solution by Nanostructured Carbonated Fluorapatite Bearing Siliceous Phosphorite

Shi, He-Bin / Liu, Yu / Zhong, Hong / Tian, Xing / Liao, Ming-Hang

A middle grade siliceous phosphorite from Yunnan province was selected to treat Cd²⁺ bearing aqueous solutions. The siliceous phosphorite was tested by X-ray fluorescence spectrometer, X-ray diffraction, infrared spectrometer and scanning electron microscopy. The results present that the valuable mineral is nanostructured carbonated fluorapatite and the major gangue mineral is quartz. The amount of Cd²⁺ sorbed by the siliceous phosphorite tends to increase with the increase of initial pH or the initial Cd²⁺ concentration of the simulated waste water. The reaction process of Cd²⁺ removal from aqueous solutions is highly fitted with the pseudo-second order kinetic model. The results indicate that nanostructured carbonated fluorapatite bearing siliceous phosphorite can effectively immobilize aqueous Cd²⁺.
