“…Median due to incidental illegal spilling (Baus et al, 2005). However, the average concentration of MTBE reported in the downstream parts of the German Rhine amounts to 0.25 lg L À1 (Achten et al, 2002) which is somewhat lower than in The Netherlands.…”

“…Atrazine and endosulfan solutions at concentrations of 10 g/L and MTBE solution at concentration of 1 mg/L in deionized water were used. The selection of the pollutants and the concentrations used in this study to prepare the synthetic solutions were based on recent studies that have identified them in high concentrations in several regions around the world [1,4,52]. The reagents used for preparation of the target pollutants solutions were of analytical grade (Fluka).…”

The aim of this study is the presentation of novel water treatment systems based on ozonation combined with ceramic membranes for the treatment of refractory organic compounds found in natural water sources such as groundwater. This includes, firstly, a short review of possible membrane based hybrid processes for water treatment from various sources. Several practical and theoretical aspects for the application of hybrid membrane-ozonation systems are discussed, along with theoretical background regarding the transformation of target organic pollutants by ozone. Next, a novel ceramic membrane contactor, bringing into contact the gas phase (ozone) and water phase without the creation of bubbles (bubbleless ozonation), is presented. Experimental data showing the membrane contactor efficiency for oxidation of atrazine, endosulfan, and methyl tert-butyl ether (MTBE) are shown and discussed. Almost complete endosulfan degradation was achieved with the use of the ceramic contactor, whereas atrazine degradation higher than 50% could not be achieved even after 60 min of reaction time. Single ozonation of water containing MTBE could not result in a significant MTBE degradation. MTBE mineralization by O3/H2O2combination increased at higher pH values and O3/H2O2molar ratio of 0.2 reaching a maximum of around 65%.

“…Different types of advanced oxidation processes (such as catalytic ozonation, photooxidation (UV/H 2 O 2 ) and (UV/TiO 2 )) are effective for MTBE removal from aqueous phase [5][6][7]. However, byproducts of the oxidation processes may remain in the treated water requiring a further removal step such as adsorption [8][9][10][11]. The adsorption process is one of the promising processes for the removal of MTBE from contaminated waters.…”

In this work, adsorptions of Methyl tertiary-butyl ether (MTBE) onto two novel adsorbents, i.e. nano-perfluorooctyl alumina was prepared using nano-γ-alumina (nano-PFOAL G ) and nano-boehmite (nano-PFOAL B ) as the supports were investigated. The surface areas of the nano-γ-alumina and nano-boehmite were determined as 265.7 and 319.5 m 2 /g, respectively. The equilibrium adsorption behavior of the nanoadsorbents was studied for adsorption of (MTBE) in a wide range (100-1,750 mg/L) of aqueous phase concentrations. The maximum adsorption capacities were 46.0 and 44.4 mg MTBE/g adsorbent for nano-PFOAL G and nano-PFOAL B , respectively. The Freundlich, Langmuir, and Brunauer-Emmet-Teller (BET) isotherms were used for modeling of MTBE adsorption on nano-PFOAL G and nano-PFOAL B from aqueous medium. The experimental results of MTBE adsorption on the surface of nano-PFOAL adsorbents obeyed a type IV van der Waals adsorption trend, which can be modeled best by the BET isotherm up to pore filling concentration.
