试样用Na_2O_2在520°—540℃下熔融,熔物用水浸出。通过阳极电流强度,载气压力及观察高度的对比实验,选出最佳工作条件的参数:阳流为0.90A,载压为2kg/cm~2,观测高度为8mm,用GSD及GSS标准样对测量精度及回收率进行了检查,相对偏差为13.6％,回收率为93％,检测限为10ppm。采用ICP法测定硼,方法简便快速,准确度高,岩石中的硼高于10ppm时,可以进行定量测定。
Sample with Na 2 O 2 melt at 520 ° -540 ℃, the melt leached. The parameters of the optimum working conditions were selected according to the comparison of the anode current intensity, the carrier gas pressure and the observation height: the positive current was 0.90A, the loading pressure was 2kg / cm ~ 2 and the observation height was 8mm. Using GSD and GSS standards The measurement accuracy and recovery rate were checked, the relative deviation was 13.6%, the recovery rate was 93% and the detection limit was 10ppm. Determination of boron by ICP method, the method is simple and fast, high accuracy, boron in the rock above 10ppm, can be quantitatively determined.
