摘　　要：为解决传统湿法消解测量土壤中金属镉、铜测量周期长、一致性差的不足,提出了一种新的基于原子吸收法的土壤中金属镉、铜快速测量技术。该技术首先采用快速消解法对土壤进行消解处理,然后再利用原子吸收法对土壤中金属镉、铜的含量进行测定。实际应用表明,新的测试技术对金属镉的测定偏差在1.89%以内,对金属铜的测试偏差在1.6%以内,新测试技术的测试时间比湿法消解测试降低了56.25%,实现了对土壤中金属镉、铜元素的快速、精确测定。In order to address the shortcomings of traditional wet digestion measurement of metal cadmium and copper in soil,such as long measurement cycle and poor consistency,a new rapid measurement technology for metal cadmium and copper in soil based on atomic absorption method is proposed.This technology first uses rapid digestion method to digest the soil,and then uses atomic absorption method to determine the content of metal cadmium and copper in the soil.Practical applications have shown that the new testing technology has a measurement deviation of less than 1.89%for metallic cadmium and less than 1.6%for metallic copper.The testing time of the new testing technology is reduced by 56.25%compared to wet digestion testing,achieving rapid and accurate determination of metallic cadmium and copper elements in soil.
