液上顶空气相色谱法快速测定尿氟的新方法周连保,杨文君,运月英目前尿氟含量的测定多采用氟电极法 ̄[1],此法灵敏度虽高但干扰因素多,电极清洗繁琐,测定微量氟往往不成对数响应 ̄[2],且误差较大。我们根据烷基氯硅烷水解产生硅醇与氟反应生成气态氟硅烷的原理...
New method of rapid determination of urinary fluoride by headspace gas chromatography Zhou Lianbao, Yang Wenjun, Yun Yuanying Determination of urinary fluoride current use of fluoride electrode method [1], the sensitivity of this method is high but the interference of many factors, the electrode cleaning cumbersome , The determination of trace fluorine often unpaired response ~ [2], and the error is larger. Based on the hydrolysis of alkylchlorosilanes, silanols react with fluorine to form gaseous fluorosilanes.
