【摘要】 <正> 离子色谱法测定水中的无机阴离子,前人已进行了研究,并列为水和废水监测分析的试行方法。吕伟等用双柱-双电导离子色谱法不经化学预分离同时测定了水样中的多种无机阴离子,本文研究了用高效单柱-单电导离子色谱法不经前处理而同时测定高含量的HCO₃^-和低含量的CL^-、SO₄^2-、NO₃^-离子的色谱条件,8min完成一个试样测定。更多还原

【Abstract】 The simultaneous determination of some inorganic anions inground water by ion chromatograph with single column-single conductivitydetector is described, Both the high concentration of HCO₃^- and lowconcentration of Cl^-,SO₄^2-,NO₃^- can be detected at the same time byShimadzu HIC-6A ion chromatograph, the low capacity anion exchangeresin is used as stationary phase and the potassium biphthalatesolution, 1.25mmol/L,pH7.3 as mobile phase. The present method canbe used to determinate microgram Cl^-,SO₄^2-,NO₃^-and milligram HCO₃^-in ground water with satisfactory results.更多还原
