We undertook a fundamental investigation of the removal of endocrine disruptors from aqueous solution by a sorption method using activated carbons, and compared the removal ability of endocrine disruptors by activated carbons to that by polydimethylsiloxane (PDMS) membranes. The activated carbons exhibited high removal ability of 1,2-dibromo-3-chloropropane (DBCP), 100 fold increased adsorption over that with PDMS membranes from aqueous solution of DBCP. The removal ratio of the endocrine disruptors, e.g., 1,2-dibromo-3-chloropropane, dibenzo-p-dioxin, and hexachlorocyclohexane, increased linearly in an aqueous solution with increasing the logarithm of P_ow of the endocrine disruptors. Almost complete removal of the endocrine disruptors (i.e.,>85%) was observed above log P_ow=3.5 in 25 mL of an aqueous solution using 0.05 g activated carbon. One aim of the present study is to use preferential sorption of chemical contaminants onto activated carbons for removal of the chemical contaminants from aqueous solutions including drinking water, beverages, milk, and human milk. When the removal of endocrine disruptors contained in milk or human milk is targeted, water soluble vitamins in the milk, such as vitamin B₂, vitamin B₁₂, and niacin are expected to be co-currently adsorbed on the activated carbons. Therefore, the present sorption method using activated carbon was applied to the removal of endocrine disruptors, such as di-n-octylphthalate, from the mineral water and 89% of di-n-octylphthalate was removed.
