本文介绍了用银离子选择电极测定铝合金中银的方法。着重试验了铝合金中常见元素的干扰情况,试验表明均不影响测定。回收率在98.0～106.8%。本法可不经分离直接测定铝合金中的银,且样品经碱溶酸化后,同时还能测定铜、铁、锰、镍。用电极法的测定结果与容量法一致。本方法具有快速、简便、准确之优点。 This article describes the silver ion selective electrode method for the determination of silver in aluminum alloys. Focus on testing the common elements of aluminum alloy interference, the test showed no impact on the determination. The recovery rate was 98.0 ~ 106.8%. This method can be directly measured without separation of silver in the aluminum alloy, and the sample after acid-base acidification, but also determination of copper, iron, manganese, nickel. The result of the electrode method is consistent with the volume method. The method has the advantages of fast, simple and accurate.
