摘要
采用微波消解技术消解处理样品，建立了等离子体发射光谱法同时检测城市污泥中微量金属元素Cu、Zn、Ni、Cd、Cr、K、B及Pb的方法。讨论了微波消解液、消解参数对消解效果的影响，在最佳实验条件下，微波消解法各元素测定结果的相对标准偏差为1．06％-3．20％（n=6），加标回收率为93．1％-104．0％。结果表明该方法精密度高，准确性好，快速简单，适于城市污泥中的重金属的测定。
An advanced method using microwave digestion and atmospheric digestion technique was developed for the simuha-neous determination of Cu ,Zn,Ni ,Cd,Cr,K,B and Pb by inductively coupled plasma atomic emission spectrometry. The experimental conditions of microwave digestion and hydride generation were optimized. The RSD of determination result by microwave digestion was 1.06% - 3.20% （ n = 6） , and the recoveries were 93.1% - 104.0%. The results showed that this method was convenient, accurate, fast and simple. It was very suitable for the determination of the heavy metals in municipal sludge.
