Partially exchanged organophilic bentonites
(Springer, 2011-09-01)
Using a sodium bentonite (VCNa) as substrate differently exchanged organophilic clays were obtained by reaction with hexadecyltrimethylammonium (HDTMA) chloride, at increasing reacting ratios (R) from 20 to 120 meq/100 g ...

Contribution of soil organic carbon to the ion exchange capacity of tropical soils
(HAWORTH PRESS INC, 2008)
Highly weathered soils represent about 3 billion ha of the tropical region. Oxisols represent about 60% of the Brazilian territory (more than 5 million km 2), in areas of great agricultural importance. Soil organic carbon ...

Cation exchange capacity and mineralogy of loess soils with different amounts of volcanic ashes
(Elsevier, 2014-05)
The cation exchange capacity of soils (CEC) is largely affected by the mineralogy of their parent material. Soils of the Argentinean Pampas develop on illitic loess, mixed, in variable proportions, with volcanic ashes. ...
Numerical simulation of cation exchange in fine coarse seawater slurry pipeline flow
(Elsevier, 2018)
Slurry pipelines transporting a coarse—the comminution product—and a fine fraction, both in the presence of
seawater, can cause an alteration of the liquid phase chemical composition. In the present paper, we present ...
