Assessment of phosphorus associated with Fe and Al (hydr)oxides in sediments and soils.

Popis výsledku v původním jazyce

Numerous extraction procedures have been used to characterize phosphorus (P) forms bound to iron (Fe) and aluminum (Al) (hydr)oxides in soils and sediments. We propose a simple modification of a widely used P fractionation method that more precisely quantifies P associated with active Fe and Al (hydr)oxides, which are mostly responsible for P binding and its potential release to water. We modified the original sequential extraction [H2O, bicarbonate-dithionite (BD), NaOH, HCl] by adding short (10-min) extractions with BD and NaOH prior to the respective original steps. The method was verified using (1) dissolution kinetics of Fe and Al minerals of different crystallinity and (2) liberation of P, Fe, and Al from natural samples of soils, sediments, andsettling seston, containing different proportions of amorphous and crystalline Fe and Al (hydr)oxides. Extracted P was analyzed for reactive and non-reactive (mostly organic) P forms. Both mineral and organic P forms associated with Fe an
