Reactions of ion-colloid forms of microcomponents and radionuclides in aqueous solutions

This monograph considers the state of the art in instrumental and combined methods used to study heterogeneous forms of physicochemical state of microcomponents and radionuclides in artificial and natural aqueous solutions. Theoretical problems of modeling of heterogeneous sorption reactions with participation of ion-molecular and colloid forms of microcomponents in equilibrium and non-equilibrium aqueous solutions are discussed. The book contains examples showing how theoretical methods for non-equilibrium physicochemical state simulation are utilized for the description of microcomponent and radionuclide migration in natural water reservoirs. The monograph presents the results of research of a new class of interphase distribution processes associated with the behavior of colloid forms of microcomponents in mutually insoluble liquids. The phenomenon of colloid chemical extraction of microcomponents is explained in terms of thermodynamics, and the results of its experimental verification are reported. Examples are given to demonstrate how this phenomenon is used to concentrate colloid forms of microcomponents and radionuclides and to determine their phase composition in natural water reservoirs.

This monograph will be interesting for specialists, postgraduates and students concerned with physicochemistry of ultra-diluted solutions, radiochemistry, radioecology and geochemistry.
