ICP法同时测定固体废物浸出液中多种金属元素

摘要

The contents of seven kinds of metal elements in Cu,Zn,Mn,Ni,TCr,Pb and Cd of solid waste leachate were determined by ICP The quality control parameters such as detection limit,precision and accuracy of the method are analyzed Under the optimized conditions,the detection limits of the seven heavy metals were 00008~0007mg/L,and the recoveries were between 850 and 110%,and the relative standard deviations were 290%~666%.%采用电感耦合等离子体发射光谱法同时测定固体废物浸出液中铜、锌、铍、镍、总铬、铅、镉7种金属元素含量.分析了方法的检出限、精密度和准确度等质量控制参数.在优化了仪器条件下,7种重金属的方法检出限为00008~0007mg/L,加标回收率在850%~110%之间,相对标准偏差为290%~666%.
