摘　　要：研究了用聚乙烯醇(PVA)、硅胶和硫酸钛为主要原料合成的水合氧化钛从模拟盐湖卤水中提取铀,分别进行了动态吸附与淋洗试验。结果表明:在模拟盐湖卤水中,水合氧化钛有较好的稳定性和吸附铀的性能,3次吸附循环中,铀回收率都在80%以上;负载树脂用饱和氯化钠溶液+清水淋洗,效果较好,动态淋洗率在99%以上。水合氧化钛有较好的耐氯根干扰能力,将其用于从盐湖卤水中提取铀的前景较好。Extracting uranium from simulative saline lake brine using hydrous titanium oxide composed by PVA,silica gel and titanic sulfate was researched.The dynamic adsorption and desorption experiments were done.The results show that the the hydrous titanium oxide has good adsorption property and stability in the simulative saline lake brine.The recovery rate of uranium is more than 80 percent in the 3times circulation.The desorption effect of uranium from the loading HTO using 2BV saturated salt water and 7BV water is the best,dynamic desorption rate is more than 99 percent.The hydrous titanium oxide can resist chloride interference and can be used to extract uranium from saline lake brine.
