Determination of heavy metal elements in acid pickle of factory by inductively coupled plasma atomic emission spectrometry
After the acid pickle of factory is treated,inductively coupled plasma atomic emission spectrometry(ICP-AES) is applied to determine heavy metal elements such as Pb,Cd,Cr,As,Cu,Ni and Zn.Under the optimized conditions,the analytical spectral lines are selected and the detection limits are determined.The proposed method is used in the analysis of the two samples of acid pickle, with values of RSD(n=9) of seven heavy metal elements in the range of 0.10%- 6.8%.
