摘要
建立了纺织品中游离甲醛的高效液相色谱检测法，采用SinoChrom ODS-BP色谱柱（250×4．6mm i．d．，5μm），流动相为甲醇-水（70：30，V／V），流速1．0mL／min，检测波长360nm。通过正交试验优化了甲醛衍生条件，应用F检验和t检验证实了本方法的准确性。方法相对标准偏差（RSD）为2．53％，回收率在95．0％～102．7％范围。
A method for the HPLC determination of free formaldehyde in textiles has been proposed. Samples were analyzed through SinoChromODS-BP column（50×4.6 mm i. d. ,5μm）. The mobile phase employed was formaldehyde-water （volume ratio 70：30） with the flow rate at 1.0 mL/min,and the detection wavelength was 360 nm. The orthogonal test has been used to optimize the derivatization of formaldehyde. The F test and the t test have been used to confirm the accuracy of this method. The relative standard deviation was found to be 2.53% ,and average recovery was 95.0%-102.7%.
