Description

Diallyl phthalate-containing 1-allyl-2-thiourea (FDA/ATU) was chemically bound on poly(styrene-co-divinylbenzene) (PSD) particle surfaces by gamma irradiation. We found that the adsorption of zinc ions increased with increasing amount of ATU on the PSD particles. The adsorption of zinc ions was strongly dependent on the pH, and the maximum effect occured in the region of pH 5–7. At pH 7, the amount of zinc adsorption increased 2.64 times compared with that of the untreated PSD particles. The adsorbed zinc ions suppressed the decomposition of Zinc bis(dimethyldithiocarbamate) (Ziram), and thus increased its adsorption capacity. In addition, the FDA/ATU-modified PSD particles could be repeatedly loaded and unloaded. Therefore, we established a simple and quick solid phase adsorption process for Ziram analysis using the FDA/ATU-modified PSD particles.
