摘要
以NBSSRM 95 1硼标准溶液为研究对象 ,测定了不同温度以及是否加入甘露醇的情况下浓缩硼酸溶液后硼的回收率和11B 10 B比值。通过分析硼回收率和11B 10 B比值随温度和甘露醇变化的趋势 ,初步得出了浓缩硼酸样品的较佳条件为 :在被浓缩样品中加入甘露醇并在 85℃左右的温度下进行浓缩。
The recovery rates and ratios of 11 B/ 10 B in NBS SRM 951 standard solution which is condensed in and not in the presence of mannitol at different temperatures are measured.Through analyzing the variations relatively good conditions for condensing HBO 3 solution are found to be:sample solution be concentrated with mannitol at the temperature of about 85℃.
