ICP-AES测试青海西台老卤水中的硼

Determination of Boron in Old Brine of Xitai Qinghai Province by ICP-AES

卤水含盐浓度大,测定难度也相对较大。本法建立了卤水经稀释后用电感耦合等离子发射光谱(ICP-AES)测定老卤水中硼元素的分析方法,同时采用内标法校正变化,本法与传统容量法相比较,测定结果比较稳合。加标回收率在94.4%~103.1%,精密度RSD达到0.97%。同时,大大缩短了分析时间,简化了分析手续,减少了大量试剂的使用。

Because of the large salt concentration in the brine,the determination of the bittern is relatively difficult.This law was established after the dilution of brine by inductively coupled plasma atomic emission spectroscopy(ICP-AES)analysis method for the determination of boron in bittern,and using the method of internal standard correction changes,compared to the traditional method and volumetric method,greatly shorten analysis time,simplifies the analysis procedures,reduce the use of a large number of reagents,save time,the determination results and measured results with traditional method after comparison are relatively stable together.The rate of recovery is between 94.4%and 103.1%,and the precision of RSD is 0.97%.
