| 摘 要： | 本文探讨了利用均相沉淀法制备的二氧化铈的脱氟行为,并利用蛇纹石作为载体,对CeO2/蛇纹石体系的除氟行为及最佳条件进行了进一步的研究,结果表明：均相沉淀法得到的二氧化铈除氟效率高,除氟容量可达11.76mg/g。以二氧化铈;蛇纹石为1：10的混合体系的除氟容量大大高于其他方法处理过的蛇纹石体系,其附近氟容量达到0.568mg/g。

| Abstract: | This paper investigates the defluorination performance of ceric oxide and ceric oxide/serpentinite obtained by homogeneous precipitation method and determines the optimal condition for defluorination. Results show that the ceric oxide obtained by homogeneous precipitation method is of great absorption capacity, about 11 76 mg/g, while the absorption capacity of ceric oxide/serpentinite is 0 568 mg/g, which is much greater than that of serpentinite treated by other method. |
