Determinación de formas solubles en agua de cationes inorgánicos en suelos, arcillas, turba, limo de aguas residuales, lodo activado y sedimentos del fondo
The content of water-soluble forms of inorganic cations (ammonium, potassium, calcium, sodium, magnesium) is one of the substantial characteristics in agrochemical, land reclamation, and sanitary assessments of soils (arable, hayland, pasturable, forest nursery soils). The cation balance should be controlled during ecological soil monitoring for the human activity impact assessment.
The measurement method is based on the extraction of water-soluble forms of cations with distilled water from a soil sample and subsequent separation, identification, and determination of analyzed components by the capillary electrophoresis method with indirect detection at wavelength of 254 or 267 nm.
