| 摘 要： | 采用目视比浊法测定工业碳酸锶中的氯化物，若溶液有色，准确定量非常困难。在溶样时加入氧化剂，利用分光光度计进行比浊。研究了在氧化剂存在下，样品的溶解、过滤对结果的影响，添加氧化剂对体系稳定性的影响，建立了用分光光度计进行比浊测定氯化物的方法，方法具有良好的线性关系，回收率在101％-106％，相对标准偏差在1．15％-3．65％，结果准确、快速，满足了生产对氯化物含量定量的要求。

| Abstract: | The determination of chloride in industrial strontium carbonate by turbidimetry with spectrophotometer is described. The influens of disolving and filtering of the sample and adding of the additive on the stability of the system and result are studied. The turbidimetry for the determination of chloride is established. This method has a good linear relationship and the recovery rate is in the range of 101% - 106% ,the RSD is 1.15% -3.65%. And also this method is accurate and rapid and can be satisfied with the requirement of quantitative analysis of chloride in strontium carbonate. |
