乙酰丙酮法测定玩具中甲醛的前处理方式探讨

Discussion on the Pre-treatment Way to Determine Formaldehyde in Toys by Acetylacetone Method

文章对乙酰丙酮法测定玩具中甲醛的两种前处理方式进行了比较。结果表明用超声提取法进行样品前处理比较快捷,高效。但部分样品表面可溶性带色附着物可能在提取过程中脱落并对甲醛的测定构成干扰。而采用直接蒸馏法提取玩具中甲醛可以有效避免这种误差,对玩具中甲醛的测定起到必要的补充作用。

The paper briefly compared different pre-treatment methods on the determination about formaldehyde in toys.The results indicated that supersonic wave extraction was quicker and more efficiency.But soluble and colored attachments of some samples may affect the determination on formaldehyde.On the other hand,distillation for formaldehyde in toys can avoid the error which plays very good supplementary function on the determination.
