摘要
采用微波消解/电感耦合等离子发射光谱法(ICP-AES)测定了城市污水处理厂污泥中Cd、Cr、Cu、Mn、Mo、Ni、Pb、Zn等8种重金属元素,并优化了ICP仪器工作参数及微波消解条件。方法的检出限为0.001~0.01mg/L,相对标准偏差为2.0%~9.2%(n=7),回收率为85.3%~105.0%。
The heavy metal elements in sludge from waste water treatment plant were determined by microwave digestion technology and ICP - AES. The parameters of ICP - AES and the best conditions in microwave digestion were investigated. The detection limits of the method were in the range of 0.001 -0.01 mg/L. The relative standard deviations were in the range of 2.0% -9.2% (n =7) , and the recoveries were in the range of 85.3% -105.0%.
