摘要
建立了应用离子色谱技术测定分子筛废液中氟含量的方法。在一定的色谱条件下,以Na2CO3与NaHCO3的混合溶液为淋洗液,以化学抑制电导检测测定分子筛废液中的氟离子含量,测定方法准确、快捷,相对标准偏差小于3%。
Method for using ion chromatography to determine fluorine ion content in molecular sieve waste liquid has been established. Under a definite chromatographic condition , with the mixed solution of Na 2 CO 3 and NaHCO 3 as wash solution , chemically suppressed conductivity detection is used to determine fluorine ion content in molecular waste liquid. This determination method is accurate , fast and its relative deviation is less than 3%.
