Abstract：The sample was dissolved by hydrochloric acid and nitric acid. After removing carbon by perchloric acid fume, the content of arsenic, copper and zinc in lead concentrate was determined in 20% (V/V) acid medium by inductively coupled plasma atomic emission spectrometry (ICP-AES) using As 188.980 nm, Cu 327.395 nm and Zn 328.233 nm as analytical lines. The results showed that the determination results of arsenic, copper and zinc were not significantly affected by matrix effect. The calibration curves were prepared by lead-free matrix matching method. The linear correlation coefficients of calibration curves were higher than 0.999 8. The detection limit of arsenic, copper and zinc was 0.032 7 mg/L, 0.024 0 mg/L and 0.130 mg/L, respectively. The arsenic, copper and zinc in lead concentrate standard sample were determined according to the experimental method. The relative standard deviations (RSD,n=7) were between 0.64% and 1.1%. The found results were consistent with the certified values and those obtained by alkali fusion ICP-AES.
