Zinc pyrithione (ZPT) is the antimicrobial substance and has been applied for various fields, including non-fouling coating paints and cosmetics. It also used for the tub part of the electronic machine with polypropylene (PP). Since the released ZPT can cause skeletal deformity or abnormality to coastal organisms, it is essential to quality check of ZPT in PP for environmental safety. However, as far as we knew, no previous reports about the analysis of ZPT in PP samples have been published; hence, we have developed a simple preparation method via extraction and precipitation. As assume that ZPT is just entrapped in the hydrocarbon chain of PP, ZPT was drawn out from the composites and homogeneously existed in the solution after untying the chain only precipitate PP with an organic solvent. This method could be applied for real manufactured samples with a low detection limit of 0.57 ppm within 10 min.

通过简单提取方法对聚丙烯中的吡啶硫酮锌的检测方法的建立

巯氧吡啶锌(ZPT)是一种抗菌物质,已应用于各种领域,包括不结垢的涂料和化妆品。它也用于聚丙烯(PP)电机的水桶部分。由于释放的ZPT可能对沿海生物造成骨骼畸形或异常,因此对于环境安全而言,PP中ZPT的质量检查至关重要。但是,据我们所知,以前没有关于PP样品中ZPT分析的报道。因此,我们开发了一种通过萃取和沉淀的简单制备方法。假定ZPT刚好被捕获在PP的烃链中,则从复合物中将ZPT抽出并均匀地存在于溶液中,然后解开链,仅用有机溶剂沉淀PP。
