what is the ion exchange capacity of china clay
Fundamentals of Soil Cation Exchange Capacity (CEC) Defining Cation Exchange Capacity Cations held on the clay and organic matter particles in soils can be replaced by other cations; thus, they are exchangeable For instance, potassium can be replaced by cations such as calcium or hydrogen, and vice versa The total number of cations a soil can hold--or its total negative charge--is the soils .

Kaolinite - Wikipedia
Kaolinite has a low shrink–swell capacity and a low cation-exchange capacity (1–15 meq/100 g). It is a soft, earthy, usually white, mineral (dioctahedral phyllosilicate clay), produced by the stone weathering of aluminium silicate minerals like feldspar.
Cation Exchange Capacity - an overview | …
Clay-loam soils, with a high percentage of clay and high cation-exchange capacity (CEC), seem to be the best choice for fertigation with OMWW. In addition, the carbonate content of the soil is important in order to exert efficient buffer power and avoid drastic changes in the pH value. The latest could cause the immobilization of different macro- and micronutrients and accelerate changes in ...
Effect of clay with different cation exchange …
PMMA/clay nanocomposites were successfully prepared by in situ free‐radical polymerization with the organic modified MMT‐clay using methyl methacrylate monomer and benzoyl peroxide initiator. Two clays with different cation exchange capacity have been used to prepare and compare the several properties. The clays have been modified using Amphoterge K2 by ion exchange reaction to increase ...

Vermiculite - Wikipedia
Vermiculite is a 2:1 clay, meaning it has two tetrahedral sheets for every one octahedral sheet. It is a limited-expansion clay with a medium shrink–swell capacity. Vermiculite has a high cation-exchange capacity (CEC) at 100–150 meq/100 g.
