Study on Iron and Manganese from Soil by Elemental Speciation

Abstract:

Elemental speciation has become an important issue in different fields of chemistry science. Research interests have moved from total element composition of the sample towards determination of species that are responsible for the biochemical and geochemical behaviour of elements. In this report, the determination of total element concentrations has been done for Fe, Mn, as essential elements with specific biological function and the determination of each soluble species of Fe(3+), Mn(2+), from soil solution and adsorptive forms on organic - mineral soil complex. The total content of analyzed microelements was as following: iron - 1058 ppm and manganese was - 430 ppm. Speciation analysis is used for the separation and quantification of different oxidation states or chemical forms of a particular element. The quantity of above soluble species in adsorptive complex or soil solution is as following: iron (3+) around - 10 ppm and manganese (2+) is - 90 ppm. The quantification of the available soluble forms of microelements is important for the soils supply with necessary nutrients in growing of plants. Keywords: elemental speciation, iron, manganese, soil
