| 摘 要： | 研究了钴、镍在硫酸盐、碳酸盐、硫化物、易溶硅酸盐、铁氧化物及难溶硅酸盐相态分析的新流程。地质样品中钴和镍经选择性溶剂定量溶解分离后，试液用ＩＣＰ－ＡＥＳ测定。该法测定国家土壤标准物质，钴、镍的ＲＳＤ％分别为４．０８％～７．８３％和０．８０％～１２．４４％，ＲＥ％小于３．６４％和３．１０％。

| Abstract: | A new procedure is used in the phase and state analysis of cobalt and nickel in sulphate, carbonate, sulphide, easy dissoluble silicate, ferric oxide and hard dissoluble silicate phases. The cobalt and nickel are quantitatively dissovled using the selective leaching reagents, before their contents are determinated by ICP AES. This method was simple, sensitive, and accurate for phase and state analysis of cobalt and nickel in geogical samples. |
