摘要
介绍了以硫脲为显色剂测定Ti-Ru-Ni合金中Ru的光度法,对钌和硫脲显色反应的最佳条件进行了试验和选择。结果表明,共存的钛和镍不干扰钌的测定,所制定方法的加料回收率为96%—102%,相对标准偏差为1.5%,测定范围为0.01%—1.00%,且操作简单,准确可靠,稳定性好。
This paper establishs a spectrophotometric methid for the determination of ruthenium in Ti-Ru-Ni alloy ueing thiourea as colour reagent.The optimum conditions for colour reaction of ruthenium —— thiourea have been studied and selected. In this method Ti and Ni coexisted in the alloy do not interfere with the determination of ruthenium,the recovery of ruthenium is 96 %—102 %,the relative standard deviation is 1.5 %,the determination range for rethenium is 0.01—1.00 %.
