Adsorption of Phthalates on the Inorganic Medium of Aquatic Environment

Abstract

Phthalates were of heath concern in groundwater and drink water. In order to understand how Phthalates were transported at different medium of the aquatic environment, adsorption experiments were conducted using quartz sand, kaolinite, and natural clay as inorganic adsorbents and sewage sludge as organic adsorbents for adsorbing Di-n-butyl phthalate and Bis(2-Ethylhexyl) phthalate. As a result, the inorganic particles displayed Langmuir adsorption characteristics. The maximum adsorption capacity is the most important parameter, varied much between the types of Phthalates than the adsorbents.
