Batch studies were performed to determine the adsorption behavior of dimethyl phthalate ester and diethyl phthalate ester on two sandy New Jersey soils at near saturation conditions. One soil had a very low organic matter content (<0.012%) while the other was quite higher (1.33%). Both esters displayed BET type adsorption to the high organic content soil, while little adsorption was displayed to the low organic matter soil. Linear, Langmuir, Freundlich, BET, and a composite isotherm proposed by Marinas and Li were fitted to the data. The composite isotherm fir best in all cases. The diethyl phthalate evidence a greater tendency to adsorb than the dimethyl phthalate.
