摘要

•Aging process made the surface of PS more hydrophilic and rough.•Aged PS adsorbed more HOCs than virgin PS due to its more O-containing groups.•EA, HB and π-π were involved in adsorption.•Differernt mechanisms control adsorption at different pH regions.•Maximum uptake for CIP and OFL occurred at pH 5.
