| 摘 要： | 以茜素红作指示剂,在pH 2.5—3.0、酒石酸-酒石酸氢钠和乙醇存在下,加入适当的掩蔽剂,用氯化钡标准溶液直接滴定高铜物料中的硫酸根,能得到与重量法一致的结果.通过对3种不同产品中的硫酸根的测定,证明本法测定快速、重现性好、准确度较高。

| Abstract: | A directly titrimetric method of barium chloride using alizarin red as indicator for the determination of sulfate in high-copper material has been studied. The titration can be completed at pH2.5-3.0 in the presence of tartaric acid-sodium acid tartrate and ethanol. The interference of copper and some metal ions can be eliminated with the addition of appropriate masking agents. Results are in good agreement with those of gravimetric method.The method has been used for determination of sulfate in copper sulfate, copper plated solutions and new agrochmicals of mixed amino acid copper complexes. |
