Development of Detection Methods for Zinc Pyrithione in Polypropylene via Simple Extraction Methods for Quality Control

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 coa...

More Information
Summary: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.
