| 摘要: |
| 用浸取剂对冶炼渣样品进行浸提,浸出液经硝酸-盐酸消解后,电感耦合等离子体光谱测定消解液中的铜、锌、镉、铅、铬、铍、钡、镍、银和砷。方法的检出限低于0.065mg/L,加标回收率为88.9%~110.6%,相对标准偏差(n=6)为0.9%~4.9%。此方法具有检出限低、再现性好、分析效率高等优点,适用于冶炼渣浸出液中危害成分的测定。 |

| 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. |
