摘　　要：介绍以EGTA荧光滴定法测定钙，以铬天青S光度法测定铝含量；其测定范围为：铝0．2％～3．0％，钙〉4％，测定结果令人满意。The content of Calcium is determined by EGTA fluorescence titration and the content of aluminum is determined by chrome azurol S photometry in this paper. The determination scope of aluminum is 0. 2% -3.0% and that of the calcium is above 4%. The determination result is reasonable.
