Study on phthalic acid esters in Chemical wastewater

Xingtao Lin

Abstract

Eight phthalic acid esters (PAEs) of environmental hormone in chemical wastewater samples from five chemical factories have been investigated. Phthalic acid esters, such as Dibutyl phthalate (DBP), Bis (2-ethylhexyl)phthalate (DEHP), Butyl benzyl phthalate (BBP) and Dicyclohexyl phthalate (DCHP), were found in the samples, but Diethyl phthalate (DEP), Di-n-propyl phthalate( DPrP), Diamyl phthalate (DAP) and Di-n-hexyl phthalate (DHP) were not detected. The concentrations of DEHP and DBP in chemical wastewater were below the threshold of wastewater discharge.
