采用电沉积法实现镧的固定,利用固定后的氧化镧去除污水中低浓度的磷酸盐,研究了不同电流、电沉积时间、温度、pH和电解液浓度条件下的除磷效果。通过显微镜观察除磷后的电极表面,以分光光度法测量除磷率,最佳除磷效果为97.2%。

Electrodeposition has been used for consolidating the lanthanum on surface of metal net. The consolidated and oxidized lanthanum can be used for removing the phosphate having low concentration from wastewater. The phosphate removal efficiency under different conditions such as current， time， temperature， pH， and electrolyte concentration has been studied. Through the observation of the electrode surface with microscope， and measurement with spectrophotometer， the phosphate removal rate is measured. The results show that the optimal phosphate removal rate is 97.2%.
