چکیده
|
Expanded polystyrene (eps) waste was chemically recycled to a novel functional polystyrene-hydrazone (psh) surface by acetylation of polystyrene (ps) and then condensation with phenyl hydrazine. the synthesized surface was characterized by the ft-ir and elemental analysis. synthesized novel functional psh surface was successfully applied for the treatment of phenol-contaminated industrial wastewater by solid-phase extraction. multivariant sorption optimization was achieved by factorial design approach. 99.93% of phenol was removed from aqueous solution. ft-ir study showed the involvement of nitrogen of hydrazone moiety of synthesized surface for the uptake of phenol through the hydrogen bonding. © 2013 ali n. siyal et al.
