Resumo

Magnetic nanoparticles of an iron oxide (Fe₃O₄) encapsulated in hyper-cross-linked polystyrene (PS) were used as a sorbent for recovery of phenols from waste waters. The encapsulated magnetic sorbent Fe₃O₄-PS was prepared by suspension polymerization. Sorption of phenol and 4-nitrophenol onto Fe₃O₄-PS was studied under dynamic and static conditions. The recovery of 4-nitrophenol was 96%; of phenol, 64%.
