  • RAPID DETECTION OF ZINC PYRITHIONE BY SERS
    Publication number: 20230243701
    Abstract: Disclosed herein is a method of detecting zinc pyrithione (ZPT) in a sample such as water, waste water, shampoos, etc. The method includes steps of, (a) contacting the sample with a substrate having a layer of metal nanostructure deposited thereon thereby coating the layer of metal nanostructure of the substrate with the sample; and (b) subjecting the sample coated substrate to Raman spectroscopy analysis; wherein, the presence of peaks at 575, 829, 1136 and 1545 cm?1 in Raman spectrum indicates the presence of ZPT in the sample. According to embodiments of the present disclosure, the method may detect ZPT in a concentration ranging from 0.1 ng/mL to 8 ?g/mL.
