Chapter 8 Process-based approach in the study of bioavailability of ions in soils

摘要: Publisher Summary This chapter discusses some recent studies and developments regarding the bioavailability issue. These include speciation measurement, modeling, ion competition for uptake, transport-controlled uptake. The general objective of these is to combine measurement modeling methods develop mechanistic approaches understand ions in terrestrial aquatic systems. an element can be expressed terms concentration free other that are involved direct Because influences all species, it likely affect therefore at least a function ion. about strong correlations obtained between metal uptake ions. An overview Donnan membrane technique (DMT) presented. Also, concepts related methods, DMT principle, setup discussed. Multisurface models including adsorption analyzed. A discussion on transport Competition also reviewed.
