%X The adsorption behavior and mechanism of dimethyl phthalate, di-(2-ethylhexyl) phthalate and di-n-octyl phthalate in drinking water with natural zeolite, two kinds of organo zeolites, and Mg/Al hydrotalcite were studied, and the adsorption properties of these clay mineral materials were compared with that of activated carbon. The results showed that the adsorption isotherms of phthalate esters on natural zeolite and Mg/Al hydrotalcite simultaneously fit Langmuir isotherms and Freundlich isotherms, and the adsorption isotherms on organo zeolites are linear. Comparing with the activated carbon, the removal efficiency of phthalate esters on natural zeolite was poor, the organo zeolites and Mg/Al hydrotalcite showed a little lower removal efficiency on small molecular size phthalate ester dimethyl phthalate and almost same removal rate of larger size phthalate esters di-(2-ethylhexyl) phthalate and di-n-octyl phthalate.
