In this contribution, we report the study of nuclear resonance magnetic spectroscopy techniques ( 1 H-NMR, 13 C-NMR, and 2D-NMR) efficiency in the characterisation of the functional composition of water-soluble organic compounds (WSOC) from atmospheric aerosols. The chosen site was our scientific...
Total suspended particles(TSP),collected from 2002 to 2003 in Guangzhou,were analyzed for the water-soluble organic compounds(WSOCs) compositions using gas chromatography-mass spectrometry(GC/MS). 采用BSTFA衍生化预处理和GC/MS分析技术,于2002─2003年对广州市荔湾区大气气溶胶中的水溶性化合物进行了定量...

Water-soluble organics in atmospheric particles: A critical review of the literature and application of thermodynamics to identify candidate compounds Abstract Although organic compounds typically constitute a substantial fraction of the fine particulate matter (PM) in the atmosphere, their molecular compositi...
Water soluble organic compounds were investigated in aerosol samples collected in a rural station in Hungary. The share of water soluble organic carbon (WSOC) reached 58% of the total carbon and 40% of the water soluble species (both organic and inorganic). Most of the WSOC was characterized ...
1) water-soluble organometallic compound 水溶性金属有机化合物 1. The syntheses and reactions ofwater-soluble organometallic compounds are also described. 特别对水相Barbier反应作了较详细的介绍,同时也描述了一些典型的水相金属有机反应,如Immonium阳离子的烷基化反应,α,β不饱和化合物的共轭加成,醇醛缩合反应...
The invention relates to water-soluble inclusion complexes of biologically active organic compounds which are insoluble or have only limited solubility in water, particularly of fat-soluble vitamins, steroid hormones, prostanoids, local anaesthetics and the like, to their aqueous solutions and to their ...
[18] indicated that highly water soluble organic compounds are most likely to be taken up by plants. The three antibiotics were detected in shoots and roots, but there were different distributions for different antibiotics. The plant root was the primary point of contact with antibiotic solution;...
