摘　　要：对乙酰丙酮分光光度法测定纺织品中甲醛含量的工作曲线稳定性进行了研究。实验结果表明,乙酰丙酮分光光度法工作曲线有良好的稳定性,相近环境温度不同贮存时间下所作工作曲线斜率的相对标准偏差(RSD)≤2.04%。The stability of calibration curve by spectrophotometric analysis with acetyl acetone as color developing reagent for determination of formaldehyde in textiles is studied in details.The results of the study show that the calibration curves of the method have good stability;the relative standard deviation of the slope of calibration curves is less than 2.04% under the close ambient temperature and different storage time.
