Competitive Adsorption of Organic Molecules on Clay Rock

Procedia Earth and Planetary Science, 2017
Abstract The processes governing adsorption of anthropogenic organic molecules on natural systems are complex. The presence of various phases in soils and mudstones may lead to various and simultaneous retention mechanisms. Adsorption experiments were performed on acetic, o-phthalic and citric acids on the Callovo-Oxfordian clay rock.

Selective synergy of 1,3-diketone for different base oil to promote the realization of oil-based superlubricity

Friction
The mixed lubricant prepared by mixing 1-(4-ethylphenyl)-nonane-1,3-dione (0206) and chelate (0206-Fe) in a ratio of 4:6 had better tribological properties than 0206.

Competitive and non-competitive adsorption of atrazine and diuron on alluvial soil

Alexandria Science Exchange Journal, 2018
The competitive and non-competitive adsorption of herbicides atrazine and diuron individual and in binary combination on alluvial soil depends upon the batch equilibration technique were evaluated. The results indicated that the optimum wavelengths obtained from spectral curves were 222 nm and 289 nm and the k values obtained from calibration curves ...
