| 摘 要： | 本文研究了测定碳酸铈中微量氯离子时酸度、铈离子浓度等因素对测定结果的影响，并建立了更为准确的测定微量氯离子的方法。研究了不同样品中氯离子的洗脱效果，证明碳酸铈中氯离子的存在形式与其制备方法有很大关系，并因此可以通过制备条件的控制来制备低氯根含量的碳酸铈。

| Abstract: | The effect of some factors on the determination of micro-amount chloride in cerium carbo nate was investigated,and a more accurate determination method of chloride was proposed,In the same time,the washing effect of chloride from cerium carbonate was also studied in this paper. It was proved that the existing form of chloride in cerium carbonate is greatly related to its prepareing process The cerium carbonate with low chloride content can be prepared by controlling its pricipitation conditions. |
