摘要
研究了以氯化亚锡作还原剂,用原子荧光光谱仪测定铜精矿中的微量汞。结果表明,原子荧光法可测定铜精矿中0.00002%~0.00012%的汞,方法线性范围在0~6μg/L,r=0.9995,检出限为0.0042μg/L,样品加标回收率在94%~98%。方法简便,准确,结果令人满意。
In this article, the stannous chloride as reducing agent, the trace mercury in copper concentrates has been determinated by AFS. The result shows: of 0.00002% -0. 00012% mercury in copper concentrates by AFS, the calibration curves of Mercury is linear in range of 0-6μg/L with r =0. 9995. The detection limit is 0. 0042μg/L. The recovery is in the range of 94 -98% . The method is simple and accurate with satisfactory results.
