摘要：采用抑制电导离子色谱方法 ,同时测定了工业废水中苯甲酸、对苯二甲酸、对甲基苯甲酸、苯磺酸、对甲基苯磺酸5种芳香酸。工业废水稀释一定倍数后,经0.22μm的过滤头和RP前处理柱处理后进行离子色谱分析。使用阴离子交换色谱分离,抑制器电导检测模式。5种芳香酸在3~40 mg/L范围内呈良好的线性,检出限低,加标回收率范围合理、操作简单、灵敏度高、重复性好、无污染,应用于工业废水中芳香酸污染物的监测,结果令人满意。
The method for the simultaneous determination of five kinds of aromatic acids,including benzoic acid,pphthalic acid,p-toluic acid,benzenesulfonic acid and p-toluenesulfonic acid,in industrial wastewater by suppressed conductivity ion chromatography has been developed. Ion chromatographic analysis is accomplished after the industrial wastewater is diluted by certain multiples,and treated via a 0.22 μm nylon filter tip,and RP On Guard column.The anion-exchange chromatography separation,and suppressor conductivity detecting mode are used. The five kinds of aromatic acids in the range of 3-40 mg/L show good linearity,low detection limit,reasonable range of tagged recovery rate,simple operation,high sensibility,good repeatability and no pollution. The results show that its application to the detection of aromatic acid pollutants in industrial wastewater are satisfactory.
