what is the cation exchange capacity of china clay

Crain's Petrophysical Handbook Clay / Shale Basics. Cation exchange capacity (CEC) is the capacity of a material, such as clay or soil, for ion exchange of positively charged ions between the clay and the surrounding water. A positively-charged ion, which has fewer electrons than protons, is known as a

what is the ion exchange capacity of china clay

Cation Exchange Capacity (CEC) Cation exchange capacity (CEC) is defined as the sum total of the exchangeable cations that a soil can adsorb Exchangeable cations are positively charged ions (eg, Na+, Ca2+, K+) held on or near the negatively charged surfaces of soil particles and which may be replaced by other positively charged ions in the soil solution.

what is the ion exchange capacity of china clay

Cation exchange occurs between soil solution and surface material such as clay, and is when the the soil solution takes an ion and in "exchange" gives of a different ion. The cation exchange capacity is primarily, most of the cation exchange, the presence of more clay will, maining cations held on exchange

CATION EXCHANGE CAPACITY AND WATER

B is specific cation conductance in (ohm −1)/(meq/ml), Qv is the cation exchange capacity (CEC) per unit pore volume: Q v = ρ g CEC 1-ϕ ϕ. Where CEC is in meq/gram of dry rock, ρ g is rock grain density in g/cc, and φ is total porosity. In clean zones (no clay), CEC=0, thus Qv=0, m*=m, n*=n, and the W-S model becomes Archie model.

Distribution and Classification of Red Soils in China

Having been subjected to intensive weathering, these soils are usually dominated by variable charge minerals such as kaolinite and Fe and Al oxides. Most red soils in China are acidic, nutrient-deficient and low in organic matter and cation exchange capacity, partly because of soil erosion and intensive use.
