顶空-气相色谱法测定玩具捏捏乐中6种苯系物

Determination of Six Kinds of Benzene Series in Pinch Toy by Headspace-gas Chromatography

近年来,儿童玩具的安全性问题受到社会高度关注。捏捏乐作为儿童玩具之一,其具有超柔、不粘手、不留残渣等优点,备受家长和小朋友的欢迎。这种玩具气味特殊、颜色鲜艳,安全性受到了质疑。本文建立了顶空-气相色谱法分离分析捏捏乐中有害物质,在最优化的色谱条件下,对各成分进行分离分析。该方法的回收率为82.03%~98.76%;精密度为0.27~3.01,线性相关性为0.9995~0.9999,结果表明该方法有效可行。该方法为儿童玩具捏捏乐中苯系物的检测提供了科学依据。

In recent years,the safety of children’s toys has received great attention.As one of children’s toys,pinch toy is very popular with parents and children because of its super softness,no stickiness,and no residue.This kind of toy has a special smell and bright colors,so its safety has been questioned.In this paper,a headspace-gas chromatography method is established to separate and analyze harmful substances in pinch toy.Under the optimized chromatographic conditions,the components are separated and analyzed.The recovery rate of this method is 82.03%~98.76%;the precision is 0.27~3.01,and the linear correlation is 0.9995~0.9999.The results show that the method is effective and feasible.This method provides a scientific basis for the detection of benzene series in children’s toys.
