Composition and antioxidant activity of anthocyanins isolated from Yunnan edi…
Edible roses (An ning) are a good source of anthocyanins and grown widely in Yunnan Province of China. In this study, the contents of anthocyanins and total phenol as well as the antioxidant activity of methanol extract from specific variety of rose were systematically investigated. The results showed that anthocyanins and total phenolic content of the petals were (353.56 ± 2.50) mg cyanidin 3…

Direct splitting of H2S into H2 and S on CdS-based photocatalyst under visibl…
Abstract. The conversion of H2S into H2 and S (H2S → H2 + S) is beneficial from both environmental and energy standpoints. Here we report that H2S can be splitted stoichiometrically into hydrogen and sulfur on CdSbased photocatalysts under visible light irradiation using ethanolamine as a H2S solvent and reaction media at room temperature. Raman spectra showed that the produced sulfur exi…

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)…

Experimental Study on the Combustion Characteristics and Emissions of Biodies…
In the present study, the combustion characteristics and emissions of biodiesel fueled direct injection engines with premixed dimethoxymethane (DMM) by port injection were investigated on a single-cylinder diesel engine. The experimental results show that, for a fixed equivalence ratio of biodiesel, the ignition timing and the center point of heat release advance, while the end point of heat re…
