| Abstract: | A fast and simple method to determine six metal elements of Cu,Zn,Ni,Cr,Pb,and Cd in sludge samples of wastewater treatment plant by aqua regia microwave digestion-atomic absorption spectrometry（AAS） was presented.The accuracy and precision of the method were examined.The recovery rate of the six elements was 86%~103%,and RSD was 1.4%~6.7%.The six metal elements in sludge samples from six wastewater treatment plants of Qingpu,Shanghai were determined using this method.The results showed it had great application with good effect. |
