An alternative to anion exchange is " cation exchange chromatography ", in which positively charged solutes bind to the solid chromatographic media.
22.
"' Sodic soils "'are characterized by a disproportionately high concentration of sodium ( Na ) in their cation exchange complex.
23.
New metamorphic minerals form through solid-state cation exchanges following changing pressure and temperature conditions imposed upon the protolith ( pre-metamorphosed rock ).
24.
For sandstone with clay minerals, this assumption is no longer true in general, due to the clay's structure and cation exchange capacity.
25.
Nutrient uptake in the soil is achieved by cation exchange, wherein root hairs pump hydrogen ions ( H + ) into the soil through proton pumps.
26.
For example, in a sulphonated polystyrene resin, a cation exchange resin, the chlorine ion of a hydrochloric acid buffer should equilibrate into the resin.
27.
Fulvic acids have a higher cation exchange capacity and therefore have a higher chemical interaction with fertilisers and are able to form soluble chelates of trace metals.
28.
This research has the potential to develop insight into the mechanisms of small scale particles such as the process of nucleation, cation exchange, and branching.
29.
Via cation exchange, it can be converted to the corresponding tetraethylammonium salt, ( N ( C 2 H 5 ) 4 ) 2 ReH 9.
30.
Many heavily leached or oxidized soils, especially in the wet tropics, have a high concentration of Al 3 + occupying the soil colloids cation exchange sites.
