The synthesized [poly(EGDMA-VIM)] microspheres were characterized by various analysis techniques. The [poly(EGDMA-VIM)] microspheres possessed a high specific surface area (304.4 m2 g(-1)). It was found that the pseudo-second-order kinetic and Freundlich isotherm models could well define the phenol adsorption process. The maximum capacity of the [poly(EGDMA- VIM)] microspheres was calculated to be 34.7441 mg g(-1) at 298 K and natural pH from Langmuir isotherm. The adsorption thermodynamics revealed that the adsorption of phenol was an exothermic and spontaneous process. The [poly(EGDMA-VIM)] microspheres were easily regenerated by using a 0.01 M NaOH solution, and were repeatedly used for at least 5 cycles without losing the adsorption capacity. The experimental results suggest that the [poly(EGDMA-VIM)] microspheres can be implemented as a promising adsorbent for phenol removal from wastewater.eninfo:eu-repo/semantics/closedAccessAqueous-solutionsGraphene oxideGlycol dimethacrylate)Contaminated waterVi microspheresWaste-waterRemovalBeadsPreconcentrationSurfactantAdsorptionN-vinylimidazoleEthylene glycol dimethacrylatePolymer microspheresPhenolScience & technologyTechnologyPhysical sciencesEngineering, chemicalWater resourcesEngineeringArticle00047292440002929030315910.5004/dwt.2019.241471944-3986
