【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。更多还原

【Abstract】 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 de- termined.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.更多还原
