Since 1860, phenol has been in production, with its basic use as an antiseptic. During late 19th century and thereafter the use of phenol has been further extended to the synthesis of dyes, aspirin, plastics, pharmaceuticals, petrochemical and pesticide chemical industries. In fact, by 2001, the global phenol production has reached an impressive 7.8 million tons. Among the different organic pollutants in wastewater, phenols are considered as priority pollutants since they are harmful to plants, animals and human, even at low concentrations. Adsorption of phenolic compounds from aqueous solutions by activated carbon is one of the most investigated of all liquid-phase applications of carbon adsorbents. Several adsorbents were used treatment wastewater and removal of phenols. Unsubstituted phenol is usually used as a model for advanced studies of wastewater treatment.
Mesoporous silica, due to large surface areas and a very narrow size distribution of mesopores, which can range 20-100 ?, are suitable for liquid phase reactions because they allow easy diffusion of the reactants to the active site.
This study aims to test the catalytic activity in liquid phase of some new mesoporous materials. The novelty consists in the catalytic systems in order to remove components harmful to the environment. The reaction products are degradation compounds, most of them not being organic compounds. The development of an efficient method will make the adsorption, a more economical and attractive option for phenol removal.
