摘要
本实验利用分光光度法对蒙药黑冰片中钛的含量进行了测定,测得标准曲线的回归方程为:A=0.00573+0.048C(r=0.9998).检测限为3~15μg/mL.回收率为99%~102%,RSD为0.89%(n=5),该方法操作简单,灵敏度高,可以推广使用.
The content of micro titanium Was determined in Hei - Bing - Plan. The regression equation is A= 0. 00573 + 0. 048C (r= 0. 9998), The examined limit is 3-- 15 μg/mL. The everage recovery was 99 % -- 102 %, and the relative standard deviationl RSD was 0.89 % (n = 5), The method is rapid, high accurate, high sensitivity and can be generalized.
