In both forest and agricultural soils, plant derived cuticular materials can constitute a significant part of soil organic matter. In this study, the sorption of nonpolar (naphthalene and phenanthrene) and polar (phenol and 1-naphthol) aromatic organic pollutants to aliphatic-rich cuticularfractions of green pepper (Capsicum annuum) (i.e., bulk (PC1), dewaxed (PC2), nonsaponifiable (PC3), nonsa...

The sorption-induced porosity and permeability alteration of coal beds as pore pressure and in-situ stress are varied can be couched within the frameworks of ‘open thermodynamic system' and ‘open-system geomechanics' (OSG). Production from coal bed methane (CBM) reservoir changes not only the fluid mass (gas and water) but also solid mass as a result of methane desorption from rock matrix. The ...

• Biochar and digestate were tested as novel sorbents for biopurification systems. • Digestate and biochar mixture enhanced the sorption coefficient by a factor of N50. • Boscalid and pyrimethanil exhibited N25 fold higher Kd/Koc values than bentazone. • Desorption was hysteretic (H ≥ 0.001) for biochar and digestate based soil

adsorption of anilofos was studied in four soils (topsoil from alfisol, inceptisol, oxisol and vertisol). the order of adsorption of anilofos was vertisol > oxisol > alfisol > inceptisol. the soil sorption coefficient k and the soil organic carbon sorption coefficient koc are the basic parameters used for describing the environmental fate of the herbicides. in top soil the calculated k values ...

IRMOF-3 nano/microcrystals with controllable morphologies and sizes were successfully obtained by a simple solvothermal method. The shape evolution of IRMOF-3 crystals from cube to truncated cube, cuboctahedron, truncated octahedron and finally to octahedron was achieved by adjusting the amount of surfactant. The surfaces of the IRMOF-3 nano/microstructures are affected by the reaction temperat...

The influence of nonlinear sorption and prior sorbate/ sorbent exposure time on transport of fenuron and monuron in laboratory soil columns was studied. Observed monuron breakthrough curves (BTCs) were well described using a two-region transport model with a single mass-transfer rate coefficient, independent of prior sorbate/sorbent exposure history. However, levels of soil-resident postelution...
