摘要
采用硝酸+氢氟酸+高氯酸全分解方法消解土壤样品,并结合原子吸收分光光度法和标准加入法测定土壤中铜、锌、铅、镉、镍、总铬的含量。结果表明,该方法具有操作简便、快速,节省试剂,准确可靠等特点;实际土壤样品的检测结果完全能满足环境土壤样品测定的要求。
A method by adding nitric acid, hydrogen fluoride and perchloric acid to completely digest soil samples was used in combination of atomic absorption spectrophotometry and standard additions for the determination of copper, zinc, lead, cadmium, nickel and total chromium contents in soil. It has indicated that this method was simple, fast, reagents saving, and reliable with satisfactory results to meet the requirements for the actual determination of soil samples.
