摘要
本文采用双毛细管在线稀释法测定矿石中高含量铅。样品经消解后定容,利用提升量比为18的双毛细管进样,用原子吸收法测定。该方法操作简便,精密度(RSD,n=10)小于1.615,适于矿石中0.x%~x×10%含量的铅组分测定。
A new method for determination of high contents of Pb in ores by AAS with on - line bi - capillary was stndied. After the samples we digested, the solution ws delivered into AAS through the bi - capillary and determined. By the determination of real samples, the precision is not more than 1.61%. The method is simple and rapid, it is efficient to determination Pb in the range from 0. x% to x × 10% in ores.
