Determination of Phthalates in Toys and Childcare Articles Made of PVC with HPLC and HPTLC

摘要

A HPLC and HPTLC method for the determination of seven phthalates in childcare articles and toys made of PVC is presented. Extraction is performed by dissolving the PVC in tetrahydrofuran. Identification and quantitation is either performed by HPLC for phthalates giving discrete peaks or by HPTLC for DINP and DIDP. The method was used for an interlaboratory test and for a market survey and proved to be suitable for supervising the legal limit of 0.1 % phthalate.
