久性有机污染物(persistent organic pollutants, POPs)之一[1],以其持久性,生物富集性及长距离迁移性等特点而广泛分布于大气,水,底泥,土壤及生物体等各环境介质中[2].由于POPs具有相对较高的蒸汽压,较低的溶解度及环境反应能力而被归属于半挥发性有机污染物(semi-volatile organic compounds, SOCs)[3-4].POPs所具有的挥... for global cycling[J]. Environmental Pollution, 2005, 134(1): 153-164. [36] Cousins I T, Gevao B, Jones K C. Measuring and modeling the vertical distribution of semi volatile organic compounds......
. The influences of different concentrations of AQS, heavy metal ions (e.g., Cu2+, Ca2+, Cr6+) and toxic organic compounds on the reduction of U(Ⅵ) were studied. The experimental results show S.putrefaciens... with their concentrations. Some toxic organic compounds, such as toluenes, trichloroacetic acid and p-nitrophenol, are capable of being utilized as electron donors to reduce U(Ⅵ) efficiently......
Progress on Study of Luminescence of Rare Earth Organic Chelates 雷衡毅1,孟建新1,杨燕生1,龚孟濂1,安保礼1,史华红1 (1.State Key Laboratory of Optoelectronic Materials and Technology, School of Chemistry and Chemical Engineering, Sun Yat-Sen University, Guangzhou 510275, China) Abstract:Based on the investigation of the luminescence of a series of rare earth organic chelates, some relationships between......
rise in the concentration of organic and inorganic compounds. Especially, the raw water is subject to elevated algae counts during summer months, which introduces process problems. The aim... of cellular organic compounds [21]. Therefore, combined treatment by pre-chlorination and coagulation is effective for removing NOM. The removal efficiencies of DOC and UV254 with combined treatment......
: nanometer oxides; La1-xSrxMnO3; organic solvent ... Analysis of pH value and citric acid capacity Citric acid is a ternary carboxylic acid, and there are different compounds with lanthanon when the pH and citric acid capacity are changed. Steady compound can......

ammonium bromide (CTAB) and acrylic acid (AA) were introduced as molecular models to study the interaction between montmorillonite and organic molecules with different charge or chain length. The compounds...Influence of Charge Density and Chain Length on the Interaction between Organic Anion and Montmorillonite郑俊萍,LI Jian,HAO Hui,YAO KangdeTianjin Key Laboratory of Composite and Functional Materials......
Introduction Catalytic hydrogenation is an essential reaction in the organic industry [1, 2]. For example, hydrogenation offers an important approach towards for reduction of nitro compounds... been reported in hydrogenation of nitro compounds into the corresponding amines, the catalysts with improved performance are still high required. Recently, MOFs (metal-organic frameworks) have been......
University Press and Springer-Verlag Berlin Heidelberg 2012 Abstract: To degrade the organic compounds in the electroplating wastewater, magnetic field was tentatively introduced into electrocatalytic oxidation on Ti-PbO2 anode. The magnetic field assisted electrocatalytic oxidation can promote anion movement and the generation of active species, resulting more organic compounds to be oxidized......
