车间空气中氟化物的气相色谱测定淄博市卫生防疫站李翠波张存玲侯学文关于氟化物的分析，国内外有许多报道。主要采用离子选择性电极法［１］、化学比色法。但前法存在着测定过程中电位漂移、氟化钠单晶膜老化响应时间过长、灵敏度较低的缺点。后法则操作繁琐、干扰因素多... Workshop Determination of fluoride in the air by gas chromatography Zibo City Health and Epidemic Prevention Station Li Cuibo Zhang Cunling Hou Xuewen On fluoride analysis, there are many reports at home and abroad. The main use of ion selective electrode [1], chemical colorimetry. However, the former method has the shortcoming of potential drift in the measurement process, long aging response time of the sodium fluoride single crystal film and low sensitivity. After the rules of operation cumbersome, interference factors and more ...
