摘　　要：研究了离子色谱法同时测定硝基苯光降解的中间产物邻硝基苯酚、间硝基苯酚、对硝基苯酚及硝酸根的分析方法.采用7.5mmol/L的碳酸氢钠,1.5mmol/L的碳酸钠混合溶液为淋洗液,紫外检测波长215nm.回收率在96.8%～101.3%之间;RSD小于1.5%;检出限在8.5×10^(-4)以下.A HPIC system was developed for the determination of o- , m-, p- nitrophenol and nitrate in photodegradation products of nitrobenzene. The eluents is the mixture solution of sodium bicarbonate(7.5 mmol/L) and sodium carbonate (1.5 mmol/L) . UV detection wavelength is at 215 nm. The recovery is ranged from 96.8% to 101.3%, the RSD is less than 1.5% and the detection limit is below 8.5×10-4.
