- In this study, new polymeric adsorbents, 2 types of polystyrene-block-poly (N-isopropylacrylamide) (PSN,
structure of hydrophobic core and hydrophilic shell), were developed and applied for removal of organic
pollutants from wastewater. Encapsulation of organic pollutants by the polystyrene-block-poly
(N-isopropylacrylamide) (PSN) resulted in increasing hydrophobicity of the polystyrene with abundant hydrophobic
spaces within the amphiphilic block copolymer. The encapsulation mechanism of BTEX by PSN
was investigated and found to be mainly attributable to the Van der Waals interactions between the aromatic
ring of BTEX and the hydrophobic core of PSN. Polystyrene-block-poly (N-isopropylacrylamide) showed
good potential as a novel and cost effective adsorbent for application to wastewater treatment, which can be
simply regenerated and reused using an external temperature changing system.
