Heavy metals in electroplating sludge leaching liquid such as Cu,Zn,Ni,Cr,Pb,Cd and Ba were determined by inductively coupled plasma atomic emission spectrometry with sulfuric acid-nitric acid extraction. The working conditions of the instrument and interference factors and elimination method were studied. Under the selected conditions,the linear correlation coefficients were all 0.999 9,the detection limits were between 0.002 mg/L and 0.01 mg/L,recoveries ranged from 93.5%to 106.0%,and the relative standard deviations of determination results were less than 10%(n=6). The method could quickly and accurately detect some heavy metals in electroplating sludge leaching liquid.
