涂料经溶剂提取或涂膜经索氏提取后,提出液中邻苯二甲酸酯类单体DEHP、DBP、BBP、DNOP可用DB-1 30.0 m×φ0.25 mm ×0.5 μm色谱柱同时分离,GC - FID或GC- MSD全扫描测定,DINP、DIDP宜采用GC - MSD选择离子扫描单独测定.采用GC - MSD测定时,方法的回收率不低于95％,DEHP、DBP、BBP、DNOP的最小检出限(LODs)均为0.04μg/mL,最低定量限(LOQ)均为0.35 μg/mL.选择扫描时,DINP、DIDP的LODs、LOQ分别为0.4μg/mL、3.5μg/mL.实验结果表明:某些丙烯酸树脂涂料以及手机外壳涂层含有高含量生殖致癌物PAEs类单体,应为制定手机涂料中邻苯二甲酸酯类有害物质最高允许限量进行评价.
