1.本文介绍了直接测定铀中微量硼的新的化学光谱法,它是基于甲醇蒸馏硼的原理,加入甲醇,将生成的硼酸甲酯加热蒸出,直接导入电弧中激发. 2.本方法测定铀及其化合物中的微量硼,下限为0.15 ppm(有可能测到0.08 ppm),结果的均方误差为±9—14%. 3.本方法标准不需基体,避免了大量基体的提纯,也节省了基体的大量消耗.同时,最大限度地避免了在电弧激发时铀蒸汽对工作人员健康的影响.
1. This article describes the direct determination of trace boron in uranium new chemical spectroscopy, which is based on the principle of methanol distillation of boron, methanol, the generated methyl borate heating steam, directly into the arc excitation. 2. The method Determination of trace amounts of boron in uranium and its compounds, with a lower limit of 0.15 ppm (with a potential of 0.08 ppm), with a mean square error of ± 9-14%. 3. This method standard does not require a matrix to avoid the purification of large amounts of matrix , But also save a lot of matrix consumption.At the same time, to maximize the avoidance of uranium vapor on the staff of the health effects of arc excitation.
