摘　　要：从含硼水溶液中提取硼酸的方法有很多,离子交换法是最有发展前景的方法之一。现在所使用的离子交换剂大多数是硼特效离子交换树脂,但是这类树脂的耐热性能不理想。研究了一种耐热性能良好且对硼的吸附量大的无机离子交换剂——水合氧化铈,考察了其对热卤水中硼的吸附及洗脱性能,得到了比较满意的结果。There are many methods to extract boric acid from the boron - containing solutions. The ion exchange method is considered the one of the most promising methods. At present, the ion exchange agents are mostly specific boron ion exchange resins, but their heat - resistant ability is not satisfying. A hydrated cerium dioxide with better heat - resistant ability and larger absorption ability was studied. Its absorption and elution ability of boron in the hot brine was investigated and satisfying result was obtained.
