摘　　要：对测定纺织品甲醛含量的乙酰丙酮比色法进行了改进。直接采用甲醛标准溶液,简化了甲醛标准曲线的制作方法。该法在测定纺织品较高浓度甲醛含量时,符合有关标准,样品加标平均回收率大于89.0%,相对标准偏差(RSD)小于6.0%(20 mg/kg添加水平除外)。该方法简便、快速、准确,适合纺织品较高浓度甲醛含量的测定。A certain progress was made in determination of formaldehyde content in textiles by acetylacetone colorimetric meth- od. With directly using formaldehyde standard solution, the drawing of standard curves could be simplified. If the formaldehyde content in textiles was high, this revised method featured simple, fast and accurate operations with recovery rate of sample a- bove 89.0% and RSD less than 6.0% （except for 20 mg/kg addition level）.
