Richard L. In sum, whereas ligand exchange with carboxylate groups is evidently the predominant DOM sorption mechanism for goethite, the DOM sorption mechanism on the HMO surface remains less defined, though carboxylates and polysaccharides appear to be involved Figs.

K F can be defined as the adsorption or distribution coefficient and represents the quantity of Ni II adsorbed onto adsorbent for unit equilibrium concentration.
You previously purchased this article through ReadCube. The adsorbed heavy metal amount q e per unit absorbent mass was calculated as follows: In acidic forest soils, Al oxides play a particularly important role in protecting organic C against microbial degradation through the formation of organo-hydroxy-Al complexes during organic litter decomposition, and potentially by Al toxicity to microbes [ 8 , 21 , 22 , 23 ].
The Freundlich isotherm is commonly given by the following non-linear equation: Stanley Whittingham.

From the journal: Miltner A, Zech W Beech leaf litter lignin degradation and transformation as influenced by mineral phases. Talanta 21 4: Barrow N, Shaw T The slow reactions between soil and anions: Whether or not the greater oxidative capacity of Mn oxides over Fe oxides translates into increased litter or DOM decomposition rates will depend on chemistry of the organic C substrate and the microbial community present among other factors [ 23 , 24 , 25 ].
Effect of time and temperature on the decrease in phosphate concentration in the soil solution. The D—R model was also applied to estimate the characteristic porosity of the adsorbent, the apparent energy of adsorption and the characteristics of adsorption on micropores rather than on a layer-by-layer adsorption [ 35 , 36 ].
