| 摘 要： | ICP-AES是土壤和沉积物中重金属理想的分析方法,很多元素通过四酸法全消解后,用其测定都可以得到理想的结果。但在用该方法测定土壤和沉积物中的钛含量时,结果严重偏低。调整前处理方法为碱熔法,选用性质较温和的熔剂,引入内标,优化实验条件后,样品经ICP-AES测定钛可得到理想的测定结果,检出限为10 mg/kg,标准偏差0.47%~1.93%(n=6),土壤回收率为84.9%,沉积物回收率为83.0%。

| Abstract: | Abstract: ICP-AES is the ideal analytical method of heavy metal determination in soils and sediments. the determination results of many kinds Elements in samples can be successfully achieved after the digestion with 4 kinds of acids, but Ti is an exception, its result is lower than thestandard, now the method of pre-treatment using Alkaline fusion is adopted, the ideal determination result is achieved using ICP-AES after the optimization of the method ,the Determination Limit is 10mg/Kg ,the recovery of the soil is 84.9%, the sediment is 83.0%. |
