| 摘 要： | 以EDTA为滴定剂,紫脲酸铵为指示剂,NH4F、酒石酸钾钠、Na2S2O3为掩蔽剂,在氨性介质中测定镍的浓度;在pH值为8.0的氨-氯化铵缓冲液中,采用滴定比色法测得钴的浓度。测得的数据与AAS法和模拟试样进行比较,结果理想。

| Abstract: | Using EDTA as titratant,murexide as indicator,sodium tartrate ammonium fluoride and sodium thiosulfate as masking agent,nickle concentration was determined in ammonic medium.And cobalt was analysed in ammonium-ammonium chloride(pH=8) by using m-Chloro-azo-antipyrine(MCAA) colorimetry.The analysis method was compared with AAS and simulated sample analysis with satisfactory results. |
