Exothermic reaction is the reaction in which the energy is released in the form of heat energy where the product form will convert the wall of the vessel hot in which the reaction is carried out.As we all know, the ammonium chloride is one of the inorganic compou...
The relative decay rate of every molecular formula was estimated by fitting a single exponential model to the change in FT-ICR-MS signal intensities over decomposition time. We found a continuous range of exponential decay coefficients (kexp) within different groups of compounds and show that for ...

Additionally, some of the molecular compounds were shared between different water samples. The DOM molecular diversity linearly correlated with the number of low-biodegradable molecules, such as, lignin-like molecules (lignins), but not with dissolved organic carbon concentration. The number of lignins...
To evaluate the advantages of using direct analysis, a C 18 extract of riverine water is compared to its whole, unfractionated water, and it was determined that the C 18 extraction is selective in that it eliminates two major series of compounds. One group is aliphatic amines/amides that are...

Natural dissolved organic matter (DOM) comprises a broad range of dissolved organic molecules in aquatic systems and is among the most complex molecular mixtures known. Here we show, by comparing detailed structural fingerprints of individual molecular f
The compound is stable in water. Analogous experiments were performed with Sc-DO3A-C4-SO3 and the same result was obtained. Figure 2 Characterization and hydrolytic stability tests of representative M-DO3A-C4-SO3 compounds dissolved in aqueous solution at neutral and alkaline pH values. (a) ...
The adsorption characteristics of low-molecular-weight organic compounds dissolved in water on hydrogenated activated carbon fibre (ACF) have been measured in terms of the amount adsorbed, the heat of immersion, and the heat of adsorptio... Y Kaneko,M Abe,K Ogino - 《Colloids & Surfaces》 被...
Iron traps terrestrially derived dissolved organic matter at redox interfaces. Reactive iron and organic carbon are intimately associated in soils and sediments. However, to date, the organic compounds involved are uncharacterized on ... T Riedel,D Zak,H Biester,... - 《Pnas》 被引量: 167...
