Characteristic of Phthalates Adsorption on the Organic Medium

Abstract:

Phthalates were of heath concern in groundwater and drink water. In order to understand how Phthalates were transported at organic medium of the aquatic environment, adsorption experiments were conducted using sludge as organic adsorbents for adsorbing Di-n-butyl phthalate and Bis(2-Ethylhexyl) phthalate. As a result, The adsorption of Phthalates by the sludge displayed Freundlich adsorption characteristics, and the much larger Freundlich affinity coefficient for Bis(2-Ethylhexyl) phthalate than that for Di-n-butyl phthalate is an indication of higher affinity of the sludge particles for Bis(2-Ethylhexyl) phthalate. By Scanning electron microscope analysis of the sludge, in principle very porous structure of the sludge would not be the limit condition and multilayer adsorption would become possible.
