摘要

工厂中的土壤重金属污染是比较常见的污染，依据HJ 491-2009《土壤总铬的测定火焰原子吸收分光光度法》标准，对某工厂土壤中重金属总铬含量进行测试，采用微波消解法和加热酸消解法分别对土壤样品进行处理，并对两种方式的稳定性和便捷性进行了分析。

Abstract

Heavy metals pollution in soil is a common pollution way in factories.Acording to HJ 491-2009 ‘Soil Quality-Determination of Total Chromium-Flame Atomic Absorption Spectrometry’,total chromium content of heavy metal dust in the soil of a certain factory is detected.Soil samples are treated by microwave digestion method and heating acid digestion method,respectively.The stability and convenience of these two methods are analyzed.
