本文提供了一个简便的对铝合金复合变质剂中间合金的全分析的测定方法。由于硅含量较高,试样溶解采用硝酸、氫氟酸和硼酸络合的办法。硼量控制在干扰以下,利用等离子体光源的稳定性,选择提升量较大的雾化器,再加之内标控制,完成了较高含量元素的测定。 This article provides a simple method of determination of the total analysis of the aluminum alloy composite modifier master alloy. Due to the high silicon content, the sample is dissolved by nitric acid, hydrofluoric acid and boric acid. The amount of boron is controlled below the interference, the use of plasma light source stability, the choice of larger amount of atomizer, coupled with internal control, completed the determination of the higher content of elements.
