摘　　要：纺织品中的7种醛类化合物与2,4-二硝基苯肼在酸性条件下衍生化反应生成各自的醛腙衍生物,采用高效液相色谱-二极管阵列检测器测定了醛类化合物的含量,建立了同时测定纺织品中7种醛类化合物的检测方法。结果表明,7种醛的衍生物得到良好的分离,各醛的质量浓度在0.15～7.5μg/m L范围内呈现良好的线性关系,相关系数均大于0.999 4,方法的平均回收率为85.4%～97.8%,相对标准偏差为0.2%～7.6%（n=7）,检出限范围为2.2～4.5 mg/kg,低于国标对相关醛类的限量要求。该方法能够满足纺织品中醛类化合物含量的测定,适用于纺织品中醛类化合物含量的分析确证。After reacted with 2,4-dinitrophenylhydrazine under acidic condition to produce hydrazone derivatives,seven kinds of aldehydes were determined by HPLC with an diode array detector. The method of simultaneous determination of seven kinds of aldehydes in textiles by HPLC was developed.The results show derivatives of seven kinds of aldehydes are well separated. In the range of 0. 15-7. 5 μg / m L,the concentrations of aldehydes present good linear relationships with correlation coefficient beyond 0. 999 4,the average recovery of the method is in the range of 85. 4%- 97. 8%,the variable range of relative standard deviation is 0. 2%- 7. 6%（ n = 7）,and the detection limit is in the range of2. 2- 4. 5 mg / kg,which is lower than the limitation requirement of Chinese National Standard. This method can be applied to detect aldehydes in textiles.
