Determination of diffusion and segregation characteristics of 32P in polycrystalline Fe ů 2.2 wt.% Si
Stloukal, Ivo ; Herzig, C.
The grain boundary diffusion of phosphorus in polycrystalline Fe ů 2.2 wt.% Si was measured using serial sectioning method with radioisotope 32P. The measurements were carried out under the conditions of the B-regime (845 ů 1173 K) and the C-regime (735 ů 830 K.
Phosphorus in aquatic ecosystems - forms, determination, cycling
Hejzlar, Josef ; Borovec, Jakub
Ecological importance of phosphorus in the aquatic environment is analysed. Starting with characterising the phosphorus chemistry and properties of its compounds in water and organisms, the paper gives an overview of external and internal sources of P for aquatic ecosystems, explains main principles of cycling within the water column and between the water column and bottom sediments and discusses relations between phosphorus concentrations and eutrophication.
