摘要
本文研究了石墨炉原子吸收测定水中铅的方法。用硝酸和高氯酸溶解水中的铅,经碘化钾和MIBK络合萃取富集,用原子吸收石墨炉法测定。该方法相对标准偏差(RSD)为3.77%,检测限(DL)为0.6μg/L-1,方法回收率在92.5%-107.3%,结果令人满意。
The method for determination of trace plumbum in water by GFASS is studied in this paper. Plumbum in water is digested by HNO3-HCLO4, then extracted and enriched with KI and MIBK, determined by GFAAS. The relative standard deviation was 3.77%,and the deteclion limit was 0.6μg/L^-1,and the recoveries were in the range of 92.5%-107.3%. Result was very satisfactory.
