摘　　要：采用低压离子色谱一电导检测器，通过过氧化氢氧化法建立纺织品中5种醛（甲醛、乙醛、丙醛、丁醛和戊二醛）的快速检测方法。分析得出分离这5种游离醛的色谱条件为：柱长14cm．洗脱流速为0．75mL／min，进样体积300μL，反应圈长度5．0m。在这种条件下，各种醛的线性范围为0．1～15．0mg／L，检出限在28～53μg/L之间，方法的回收率高于96．7％，该方法成功应用于纺织品中醛类的在线测定，准确度高。The method of hydrogen peroxide oxidation followed by Low Pressure Ion Chromatography-conductivity detector has been developed for fast determination of five aldehydes （formaldehyde, acetaldehyde, propionaldehyde, butyraldehyde and glutaraldehyde） in textiles. The chromatographic conditions of the method： column length is 14 cm, elution flow rate of is 0.75 mL/min, injection volume is 300 μL, reaction loop length 5.0 m. Under these con- ditions, the linear range is 0.1-15.0 mg/L, the quantification limits for the desired compounds ranges from 28 μg/L to 53 μg/L, and the recovery is higher than 96.7%. The proposed method can be successfully applied to online determination of the target compounds in textiles with a higher sensitivity.
