mesoporous carbon adsorbents
Project description

The recently developed ordered mesoporous carbon materials (OMCs) via the organic-soft organic template method (convenient and durable process), are potential candidates for the next generation of low-cost but highly efficient adsorbents to remove organic pollutants. The effect of the adsorption characteristics, M. N. pore volume, pore diameter, symmetry, specific surface area and functional groups on the surface, of the OMC's on the adsorption behavior to date is only been studied in a qualitative manner. This project is based on a quantitative approach to the adsorption characteristics. For this purpose, will OMCs be synthesized with different adsorption characteristics by varying at carbonization temperatures, by the use of different templates, of different koolstofprecursoren and with / without functionalization. The adsorbates model are organic molecules with different size, polarity and functional groups, such as bisphenol A, carbamazepine, and 17-beta-estradiol-acetate. This model molecules are pollutants which belong to the so-called "emerging pollutants" which, according to the Water Framework Directive 2015 must be removed from water. The synthesized adsorbents will first significant adsorbenskarakteristieken, i.e. the adsorbensdescriptoren be determined by screening. Then, the equilibrium and the kinetics of the adsorption process will be measured and be modeled. In the model parameters and the adsorbensdescriptoren adsorbaatkarakteristieken will be recorded. With the aid of these models, the appropriate descriptorwaarden are determined which correspond to the ideal adsorbent for an optimum operation. Final these adsorbents are synthesized and to be validated.
