Adsorption behavior of petroleum asphaltenes dissolved in Toluene by low-cost mineral adsorbents
This paper presents the feasibility of the removal of asphaltenes from aqueous solutions by using low- cost natural adsorbents such as light expanded clay aggregate (LECA), perlite and bentonite. The structure of adsorbents was characterized by XRD, FTIR, and SEM before and after the adsorption of asphaltenes. The effect of the adsorbent type, initial asphaltene concentration, particle size of ...
متن کاملTCE adsorption by GAC preloaded with humic substances
ranular activated carbon (GAC) adsorption has been identified by the Safe Drinking Water Act amendments of 1986 as the best available technology for removing synthetic organic contaminants (SOCs) from drinking water supplies.1 GAC is particularly suited for treating water because it effectively removes a wide range of organic compounds and can protect water supplies from such transient occurren...
متن کاملExport of dissolved carbonaceous and nitrogenous substances in rivers of the "Water Tower of Asia".
Rivers are critical links in the carbon and nitrogen cycle in aquatic, terrestrial, and atmospheric environments. Here riverine carbon and nitrogen exports in nine large rivers on the Tibetan Plateau - the "Water Tower of Asia" - were investigated in the monsoon season from 2013 to 2015. Compared with the world average, concentrations of dissolved inorganic carbon (DIC, 30.7mg/L) were high in r...
متن کاملGamma ray decomposition of dissolved organic substances in river water without compositional change of metallic elements.
A river water sample was irradiated with 60Co gamma-rays under aerobic conditions, and the changes of the organic substances in the sample were examined by the analyses of the dissolved organic carbon (DOC), organic composition, UV spectrum and molecular-weight distribution. By the irradiation, the DOC decreased with irradiation dose following the first-order kinetics. In addition, the changes ...
متن کاملProduction of macroaggregates from dissolved exopolymeric substances (EPS) of bacterial and diatom origin.
Exopolymeric substances (EPS) isolated from a pure culture of the marine bacterium Marinobacter sp. and the marine diatom Skeletonema costatum (axenic) were partially purified, chemically characterized and used as dissolved organic matter (DOM) for the production of macroaggregates. The role of organic particles such as transparent exopolymeric particles (TEP) and Coomassie stained particles (C...
