The Lower Cation Exchange Capacity Limit of Montmorillonite

Organic Pillared Clays

“…The amount of pore volume in the interlayer space is higher using low charged smectites. Additionally, a low layer charge of the smectite also decreases the hydrophilic properties of the interlayers (41). Both effects increase the adsorption using lowcharged smectites.…”

“…It is expected that the best suited smectites for RPC have a very low charge, where the volume loss through the cations can be neglected. Unfortunately, the swellability of any smectites is related to the layer charge (41). Below a certain value of layer charge only parts of the FIG.…”

Sorption characteristics of oxytetracycline, amoxicillin, and sulfathiazole in two different soil types

“…Soils were air-dried and sieved through a 2-mm sieve. Soil pH was determined in a 1: 5 soil-to-water suspension after stirring for 2 h. The cation exchange capacity was measured with standard acetate ammonium procedure (Meir and Nuesch, 1999). The organic matter was determined according to the method of Tyurin (1951).…”

Chemical modification routes of synthetic talc: Influence on its nucleating power and on its dispersion state

“…Indeed, during the synthesis of synthetic talc, an amount of byproduct can be obtained. This byproduct called stevensite has cations located in the interlayer and is therefore a candidate for cation exchange (Meier and Nuesch, 1999;Chastek et al, 2007;Chabrol et al, 2010).…”
