Phthalates

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
