| Abstract: | Hazardous ingredients such as copper,zinc,cadmium,lead,chromium,beryllium,barium,nickel,silver and arsenic in smelter slag were extracted with leach liquor,digested by HNO3-HCl solution,and determined by inductively coupled plasma atomic emission specrometry.Under the optical conditions,the detection limits were lower than 0.065 mg/L.The standard addition recoveries were 88.9%～110.6%,and the relative standard deviation(RSD,n=6) was 0.9%～4.9%.This method showed low detection limit of tested metals,good repetition,high analysis efficency and was applicable in the determination of hazardous ingredients in smelter slag. |
