提出了同时测定环境样品中挥发性有机酸及乳酸的离子排斥色谱法（IEC法）。考察了流动相浓度、流速对有机酸分离的影响。实验结果表明,乳酸、甲酸、乙酸、丙酸、正丁酸和正戊酸可达到完全分离,被测组分的浓度与其峰高在一定的范围呈良好的线性关系,检出限均低于0.10 mg/L。测定了糖蜜酒精废水和消化污泥中有机酸的含量,结果满足检测的要求,样品中各组分的相对标准偏差为2.2%～5.6%。
提齣瞭同時測定環境樣品中揮髮性有機痠及乳痠的離子排斥色譜法（IEC法）。攷察瞭流動相濃度、流速對有機痠分離的影響。實驗結果錶明,乳痠、甲痠、乙痠、丙痠、正丁痠和正戊痠可達到完全分離,被測組分的濃度與其峰高在一定的範圍呈良好的線性關繫,檢齣限均低于0.10 mg/L。測定瞭糖蜜酒精廢水和消化汙泥中有機痠的含量,結果滿足檢測的要求,樣品中各組分的相對標準偏差為2.2%～5.6%。

Volatile organic acids and lactic acid in the environmental samples were simultaneously determined by ion exclusion chromatography（IEC） method.The concentration and velocity of mobile phase were examined for the effects to the separation of organic acids.The results showed that lactic acid,formic acid,acetic acid,propionic acid,butyric acid and pentanoic acid were completely separated.The measured concentrations of organic acids showed good linear relationships with those peak heights in a certain range.The detection limits were less than 0.10 mg/L.The concentrations of organic acids in molasses alcohol waste and digested sludge were determined and the results met the testing requirements.The relative standard derivations were from 2.2% to 5.6%.
