摘　　要：通过乙基己二醇-三氯甲烷萃取姜黄比色法对市面上销售量较大的3种(超轻黏土、水晶泥、史莱姆)15批软泥类玩具中的硼元素含量进行了测定。结果显示,当硼元素质量浓度在0.037~0.187μg/mL范围内时该方法线性良好,相关系数R为0.9979,平均回收率在85.52%~106.99%之间。检测结果表明,超轻黏土类样品中硼元素含量在654~694 mg/kg之间;水晶泥类样品中硼元素含量在324~371 mg/kg之间;史莱姆类样品中硼元素含量在314~381 mg/kg之间。在所有检测的几类软泥玩具中,只有超轻黏土类样品符合欧盟标准EN 71-3∶2019中规定的硼限量要求。In order to understand the content and harmfulness of boron in soft clay toys,the ethylhexanediol-trichloromethane extraction-turmeric colorimetry method is employed to determine boron content in 3 kinds of soft clay toys(ultra-light clay,crystal mud and slime toys)with large sales volume.The results show that boron content determined by this method has a good linearity in the range of 0.037-0.187μg·mL^(-1),the correlation coefficient R is 0.9979,and the average recovery rate is between 85.52%and 106.99%.It is shown from determination results that the content of boron in ultra-light clay toys samples is in the range of 654-694 mg·kg,that in crystal mud toys samples is in the range of 324-371 mg·kg^(-1),and that in slime samples is in the range of 314-318 mg·kg^(-1).Among the samples determined,only ultra-light clay toys sample can meet the limit requirements of the EU standard EN 71-3∶2019 on the content of boron.
