Abstract
Poly(2-cinnamoylethyl methacrylate)-block-poly(acrylic acid) (PCEMA-b- PAA) nanospheres are soluble in water. The lightly cross-linked PCEMA cores of these nanospheres can uptake perylene, a polycyclic aromatic hydrocarbon (PAH), from water. Reported are the rate of perylene incor poration into the nanosphere cores and the coefficient of perylene par tition between the cores and water. Also the nanospheres were shown to precipitate completely with the addition of sufficient divalent catio ns such as Ca2+ and redisperse with EDTA. which complexes with Ca2+. T hese nanospheres should be useful in concentrating PAHs present in tra ce amounts in water for chemical analysis or in the reclamation of wat ers contaminated by PAHs.
