Fedotov, M. Statkus, G. Tsizin] Effective mass-transfer coefficients of elements in their dynamic extraction from soils, silts, and bottom sediments in a rotating coil column were calculated with the use of the deterministic model of sorption/desorption dynamics describing the behavior of a microcomponent in the system stationary solid sorbent-mobile liquid phase. It was demonstrated that on-line fractionation of element forms in a rotating coil column allows not only a more correct (in comparison with successive extraction in the static mode) determination of heavy metals and arsenic in the most mobile and biologically accessible fractions, but also the prediction of the dynamics of the element release with changing environmental conditions.
