摘　　要：优化了分子荧光法测定硼-变色酸络合物的实验条件,提出了一种新的形态分析方法-连续浸提法。方法检出限为3.28μg/L,相对标准偏差为3.91%。该方法应用于银杏叶中不同形态硼含量的测定,结果满意。Under the Optimal experimental conditions,boron-chromotropic acid method based on molecule fluorimetry was adopted for the speciation analysis as a sequential chemical extractions. The detection limit is 3.28μg/L,and RSD is 3.91%. This method was applied to determination of different speciations of boron in gingko leaf,with satisfactory results.
