| Abstract: | Inductively coupled plasma optical emission spectrometry(ICP-OES) was applied to determine metal impurities Al,Mn,Fe,Co,Ni,Cu,Zn,Cd,Sb and Pb in chromium electroplating bath.Working parameters of the instrument were optimized,and suitable analytical lines were selected.The effect of matrix and coexistent elements on the determination was studied.It was found that the detection limits for the 10 kinds of metal impurities were in a range of 0.15~43.63 μg/L.The concentration of various metal elements was linearly proportional to the signal intensity,and the linear correlation efficient was equal and/or above 0.999 9.In the meantime,the established method had a good precision for the determination of various metal impurities in the electroplating bath,showing a relative standard deviation of below 3.5% and a sample recovery of 90.11%～107.60%. |
