Synthesis and Evaluation the Adsorption Capacity of Phenol in Water of the Copolymer (Divinylbenzene-styrene) Material

Abstract

Abstract: Copolymer (divinylbenzene-styrene) foam was synthesized with free radical copolymerization by suspension method. Characteristic properties of the material are by IR spectrometry, scanning electron microscopy (SEM), DSC-TGA thermal analysis. The specific surface area and porosity of the material were evaluated by BET method, the maximum adsorption capacity and the factors influencing the process of adsorption of phenol in water of porous copolymer material survey. The copolymer material has a porous network structure, the specific surface area determined by BET is 589.45 m²/g, Langmuir equation is 866.14 m²/g, the average porosity is 3.5-20 nm. The effect of time, pH, initial solution concentration on the adsorption phenol of the material was investigated. Materials for the maximum adsorption to phenol in water reached 75.2 (mg/g).

Keywords: Porous polymer, copolymer (divinylbenzene-styrene), phenol.
