摘要
本文建立了一种城市污泥多种重金属含量快速测定的方法:以1+1王水为消化体系在石墨消解仪上对城市污泥标准物质进行前处理,ICP-OES同时测定消解液中镉、钴、铬、铜、锰、钼、镍、铅、锶、钒、锌、砷12种元素,发现各元素含量均在标准值范围内,城市污泥实际样品应用研究发现各元素RSD在0.47%~8.4%,加标回收率在84.3%~110%。
A rapid method for the determination of multiple heavy metals in urban sludge was established.The reference material of municipal sludge was pretreated with 1+1 aqua rega as the digestion system on graphite digestion instrument.Thirteen elements including cadmium,cobalt,chromium,copper,manganese,molybdenum,nickel,lead,strontium,vanadium,zinc and arsenic in the digestion solution were determined by ICP-OES.The contents of all elements are within the standard value range.The RSD of all elements were 0.47%~8.4%,and the recoveries of all elements were 84.3%~110%.
