多波长分光光度法同时测定铝和镓

Simultaneous Determination of Aluminium and Gallium with Multi-wavelength Spectrophotometry

本文确定了以ＰＡＲ为显色剂同时测定铝和镓的条件，并用矩阵法计算，两元素的比例在１／１０或１０／１的范围内结果较好，回收率满意。

In this paper,the optimum condition of using PAR as a developer to determine Al andCa is worked out.By calculation with least square method in matrix form,it is found that theproportion of the two elements is good to be kept within the range of 1/10 or 10/1,and therecoverv is satisfactory
