离子色谱法同时测定透析用水中痕量氟、氯、硫酸根和硝酸根
Simultaneous Determination of Trace F-,Cl -,SO2 -4 and NO 3 in Hemodialysis Water by-Conductance-Ion Chromatography
摘要
Abstract
The simultaneous determination of trace F -,Cl -,SO2 -4 and NO 3 in hemodialysis water by chromatography was introduced-in this paper. Sample volume,eluent concentration and checker current were optimized by operation. The detection limits of F -,Cl, SO2 --4 and NO 3 are 0. 012,0. 014,0. 074 and 0. 016 mg/ L,respectively. The recovery rates are in the range of 90% and 110% . The environmental standard (204715)was tested six times. The anion concentration is in range of twice as large as recommended value uncertainty. Relative standard deviation is less than 2% . This method has the advantages of rapidity,high sensitivity and accuracy, which can be used for determining F -,Cl -,SO2 -4 and NO 3 in hemodialysis water simultaneously.关键词
