用连续流动分析法测定烟草中的钙

Determination of Calcium Content in Tobacco by Continuous Flow Analysis Method

摘要: 采用流动分析仪测定烟草中钙的含量，并进行重复性和回收率的测定。结果表明，测试样品的变异系数均在3%以内，具有较好的重复性，平均回收率达到100.98%，说明该方法具有一定的可行性。

Abstract: We explored a method for the determination calcium content of tobacco by using continuous flow analyzer and studied on the repeatability and recovery. The results showed that the method had good reproducibility. The variation coefficient was less than 3% and the average recovery reached 100.98%.
