| Abstract: | The method for determining nickel released from imitation jewelry by inductively coupled plasma atomic emission spectrometry was established. The plasma flow rate was 15.0 L/min, the observation height was 10 mm and the analytical line of nickel was 231.604 nm. The content of nickel was linear with response of the instrument in the range of 0-5 mg/L with linear correlation coefficient of 0.999 9. The relative standard deviation of 2.0 mg/L nickel standard solution detection results was 1.9%（n=6） and the detection limit was 8 μg/L. The reference material was detected by the method and the results were in the range of reference value. |
