Influence of activated carbon surface chemistry and structure on the fulvic acids adsorption from water solution [PDF]

, 2008
Количественно оценено влияние химии поверхности и структуры активного угля на адсорбируемость фульвокислот из водных растворов. Для оценки энергии адсорбции различных фракций фульвокислот использован метод "условного компонента".

Effects of humic and fulvic acids on poliovirus concentration from water by microporous filtration. [PDF]

, 1985
Because naturally occurring organic matter is thought to interfere with virus adsorption to microporous filters, humic and fulvic acids isolated from a highly colored, soft surface water were used as model organics in studies on poliovirus adsorption to ...

Influence of Some Washing Powder Components on Copper (II) and Calcium (II) Complexation with Fulvic Acids

, 1997
International audienceThe complexation of mixed ligand solutions with Cu(II) and Ca(II) is studied. The systems contain fulvic acids as natural ligand, and a phosphonic acid (nitrilotris(methylenephosphonic acid), ATMP, or 1-hydroxyethane-1, 1 ...

Water-Stable Aggregates and Associated Carbon in a Subtropical Rice Soil Under Variable Tillage

Revista Brasileira de Ciência do Solo, 2016
Tillage systems can influence C sequestration by changing aggregate formation and C distribution within the aggregate. This study was undertaken to explore the impact of no-tillage without straw (NT-S) and with straw (NT+S), and moldboard plow without ...
