Ozonation catalyzed by the raw bauxite for the degradation of 2,4,6-trichloro…
Abstract. A kind of inexpensive and environmental friendly mineral, the raw bauxite has been used successfully as a catalyst combined with ozonation in the degradation of 2,4,6-trichloroanisole (TCA). The catalyst was characterized by using various analytical techniques. X-ray powder diffraction (XRD) characterization showed that the raw bauxite containing boehmite (y-AlOOH), kaolinite (Al…

Inhibiting the regeneration of N-nitrosodimethylamine in drinking water by UV…
Abstract. N-Nitrosodimethylamine (NDMA) is a highly carcinogenic compound that is suspected of carcinogenic activity in the human body. A variety of methods are used to remove NDMA from water, but the main degradation products, dimethylamine (DMA) and NO2−, are also precursors for NDMA formation. UV irradiation combined with ozonation (UV/O3) was examined in this investigation for its abi…

Influence of surface texture and acid–base properties on ozone decompositio…
Abstract. The decomposition of aqueous ozone in the presence of three aluminum (hydroxyl) oxides was studied, respectively. It was hypothesized that surface hydroxyl groups and acid–base properties of aluminum (hydroxyl) oxides play an important role in catalyzed ozone decomposition. The variables investigated were oxide dose, aqueous pH, presence of inorganic anions (sulfate and nitrate)…

Conformation-Specific Pathways of B-Alanine: A Vacuum Ultraviolet Photoioniz…
We report a photoionization and dissociative photoionization study of B-alanine using IR laser desorption combined with synchrotron vacuum ultraviolet (VUV) photoionization mass spectrometry. Fragments at m/z =45, 44, 43, and 30 yielded from photoionization are assigned to NH3CH2CH2+, NH2CHCH3+, NH2CHCH2+, and NH2CH2+, respectively. Some new conformation-specific dissociation channels and co…
