Analysis of Phthalate Ester Content in Polyvinylchloride Construction Plastics by RAMAN Spectroscopy

Abstract:

There is serious concern that fat-soluble phthalates such as di (2-ethylhexyl) phthalate, or DEPH. Phthalates are not chemically bonded to the PVC and will with time escape by evaporation or by extraction when in contact with liquids. Raman spectroscopy excited with a 785 nm laser can be used to determine the content of plasticizers in commercial flexible polyvinyl chloride (PVC) construction plastics. This method is very convenient for rapid non-destructive remote determination of phthalates, such as for quality control of production lines, quality control or at customs.
