Abstract

Batch adsorption of 4-nitrophenol (4-NP) from aqueous solutions on some non-ionic porous copolymers based on the styrene and divinylbenzene was investigated. The adsorption studies were performed as a function of various parameters: contact time, initial concentration of 4-NP solution and adsorbent/adsorbate ratio. Equilibrium and kinetics studies were investigated. Also, from the adsorption data the specific surface area of the polymeric adsorbents has been determined. The results showed that the porous beads prepared in presence of porogen mixture (toluene:gasoline) could have potential applications in the treatment of environmental pollution caused by 4-NP.

Keywords: adsorption; 4-nitrophenol; styrene-divinylbenzene copolymer; isotherm models
