碱卤化合物色心晶体中微量OH^-的测定及其分布

Determination of Trace OH^-in Alkali-Halide Color Center Crystal and Its Distribution

本文研究碱卤化合物色心晶体中,微量0H^- 的最佳分析条件和提高检测灵敏度。减少晶体样品的使用量(0.1—0.2g),扩大分析浓度的线性范围(0—24ppm)制作测定和分析KCl,NaCl晶体的工作曲线,结果满意。还对大小为30×60mm的NaCl单晶进行剖析实验,探讨其中OH^-的分布状态以及有关结果的分析。

With the purpose of the determination of trace OH^- in alkali-halide color center crystal, this paper deals with the optimal condition of analysis as well as the means of enhancing the sensitivity of OH^- detection and redueing crystal sample amount (0.1-0.2g)and extending the linearity range of analytical concentration (0-24ppm). A working curve for determining trace OH^- is made and applied to the sampling analysis of KCl and NaCl crystals with a satisfactory result. Within a single. NaCl crystal of 30×60 mm the distribution of OH^- is studied in detail by split test.
