Gas-to-Aerosol Phase Partitioning of Atmospheric Water-Soluble Organic Compounds at a Rural Site in China: An Enhancing Effect of NH3 on SOA Formation.

Environmental Science and Technology, 2022
Partitioning gaseous water-soluble organic compounds (WSOC) to the aerosol phase is a major formation pathway of atmospheric secondary organic aerosols (SOA). However, the fundamental mechanism of the WSOC-partitioning process remains elusive.

Preparation of water-soluble dialdehyde cellulose enhanced chitosan coating and its application on the preservation of mandarin fruit.

International Journal of Biological Macromolecules, 2022
Biopolymers, e.g., polysaccharides and protein, have been employed as edible coatings for the preservation of fruits for many years and are the promising candidates for resolving the problems caused by the extensive using of synthesized polymers in ...

Insights into measurements of water-soluble ions in PM2.5 and their gaseous precursors in Beijing.

Journal of Environmental Science, 2021
To better understand the characteristics and transformation mechanisms of secondary inorganic aerosols, hourly mass concentrations of water-soluble inorganic ions (WSIIs) in PM2.5 and their gaseous precursors were measured online from 2016 to 2018 at an ...

The determination of chromium in water-soluble polymers by gas chromatography

Analytica Chimica Acta, 1981
Abstract Water-soluble polymers have found increasing use in the areas of water treatment, paper production and oil recovery, and the determination of heavy metals in such materials is important from an environmental standpoint. Heavy metal contamination could result from redox catalysts in the polymerization system, raw materials or stainless steel ...

Microbial degradation of the water-soluble fraction of gas oil—I

Water Research, 1978
Abstract The microbial degradation of the water-soluble components of gas oil was measured both qualitatively and quantitatively. The mixed autochthonous flora in clean ground water served as the inoculum in continuous percolation experiments. Concentration gradients of individual compounds as well as of DOC were measured as a function of the ...

Experimental and theoretical study on water solubility of carbon dioxide in oil and gas displacement

Journal of Petroleum Science and Engineering, 2021
Abstract The emission of greenhouse gas carbon dioxide causes the global temperature to rise year by year. A possible method for CO2 storage and emission reduction is to use it to displace oil and gas. Solubility of CO2 in water is key to replace oil and gas.

Gas-liquid-liquid reaction using water soluble catalyst

Chemical Engineering Science, 1992
Abstract Industrial applications of homogeneous catalysis by precious metal complexes are limited due to the difficult recovery or regeneration of such catalysts. By using water soluble phosphorous ligands, the catalytic complex can be kept in aqueous phase.

Preparation of water soluble poly(aniline) and its gas-sensitivity

Green Chemistry, 2005
Water soluble poly(aniline) was prepared using the chemical oxide method by adding a small amount of poly(sodium-p-styrenesulfonate). Poly(aniline) composite film on interdigital electrodes of carbon was formed via the spin-coating approach. After pretreatment of exposure in an alkalescence atmosphere and desorption with high-purity N2, the film showed

Batch Treatments of Deep Gas Wells Using Water-Soluble Corrosion Inhibitors

SPE Deep Drilling and Production Symposium, 1981
ABSTRACT Batch treatments of deep gas wells are common methods of corrosion control in West Texas. The majority of the batch-treated wells are treated with an oil-soluble, water-dispersible corrosion inhibitor mixed with a hydrocarbon solvent.

Gas-Phase Conversion of Oxide Phases of Lanthanides and Uranium to Water-Soluble Compounds

Radiochemistry, 2020
Gas-phase conversion to water-soluble compounds of individual rare-earth element (REE) (La, Ce, Pr, Nd, Sm, Eu, Dy, Ho, Er, Tm, Lu) oxides and oxide systems (U,Ce)Ox and (U,Nd)Ox in the atmospheres HNO3 (vapor)–air and NOx–H2O (vapor)–air was examined. It was shown that water-soluble compounds are formed in the gas-phase conversion of REE oxides in the
