It also has a high cation-exchange capacity, which also supports the larger biomass.

These are the values reported by Carroll (1959) for the cation-exchange capacity of minerals in meq.

The term "active" represents a ratio of the cation-exchange capacity to clay of the pedon.

The attenuation of heavy metals (or the taking up of metals by plants) can depend on clay content and cation-exchange capacity.

Closely related to cation-exchange capacity is the base saturation, which is the fraction of exchangeable cations that are base cations (Ca, Mg, K and Na).

Soil acidity or soil pH and cation-exchange capacity: Root cells act as hydrogen pumps and the surrounding concentration of hydrogen ions affects their ability to absorb nutrients.

Cation-exchange capacity (CEC) is the amount of exchangeable cations per unit weight of dry soil and is expressed in terms of milliequivalents of hydrogen ion per 100 grams of soil.

In soil science, cation-exchange capacity (CEC) is the maximum quantity of total cations, of any class, that a soil is capable of holding, at a given pH value, available for exchange with the soil solution.

Thus, a soil with high cation-exchange capacity takes longer time to acidify (as well as to recover from an acidified status) than a soil with a low cation-exchange capacity (assuming similar base saturations).

Capillary electrochromatography - A new alternative in ion separations.

Fast separation of pyrimidine derivatives by capillary electrochromatography on ion-exchange/reversed-phasemixed-mode stationary phases.

Capillary electrochromatography is a combination of two analytical techniques, High performance liquid chromatography and capillary electrophoresis.

In capillary electrochromatography capillaries, packed with HPLC stationary phase, are subjected to a high voltage.

Investigations on the behaviour of basic compounds in ion-exchange capillary electrochromatography and capillary electrophoresisusing low pH carrier electrolytes.

This subsequently led to Capital HPLC becoming in 1989 the first commercial organisation to have an active research programme into the exciting new science of capillary electrochromatography.

Capillary electrochromatography (CEC) is a chromatographic technique in which the mobile phase is driven through the chromatographic bed by electroosmosis.

Capillary electrochromatography (CEC) combines the principles used in HPLC and CE.
