Bismuth(III) Halide Complexes: New Structural Types and New Application Areas

Adonin S.A., Sokolov M.N., Fedin V.P.

Abstract

Recent advances in studies of bismuth(III) halide complexes (HBs) are reviewed concisely. New structural types of HBs and some of their physical properties that show the greatest promise for application and attract the greatest attention of researchers are discussed.

Trends in Sorption Recovery of Platinum Metals: A Critical Survey

Ehrlich H.V., Buslaeva T.M., Maryutina T.A.

Abstract

The major trends in research into the sorption recovery and separation of platinum metals are critically surveyed. The advantages and disadvantages are described for ion-exchange and complexing sorbents based on organic polymers, chemically modified silicas, sorbents with applied macrocyclic compounds, hybrid organomineral sorbents with supported polymers, molecular imprinted sorbents, solid-phase extractants based on ionic liquids, biosorbents, and other types of sorbents. The technological potentials of these sorbents are evaluated.

Structural Aspect of Glass Formation in Aqueous Electrolyte Glass-Forming Systems

Kirilenko I.A.

Abstract

Water–electrolyte systems containing aqueous solutions of Group I–III metal, transition metal, and lanthanide nitrates, iodates, sulfates, acetates, orthophosphates, chlorides, and fluorides, inorganic acids, as well as aqueous and nonaqueous solutions of some of organic compounds (alcohols, acids, aromatic hydrocarbons) have been studied. The research methodology developed at the Institute of General and Inorganic Chemistry, RAS, and the analysis of experimental data have no analogues in our country and abroad. On the basis of the results obtained, general tendencies of glass formation in various water–electrolyte systems have been revealed. For the first time, a polymeric structure of glass-forming compositions of a number of water–electrolyte systems has been proved. The assumption is made that the nature of glass formation in water–electrolyte systems is the same as in systems containing “classical glass” (phosphates, silicates, and others) and organic glass-forming systems, that is, polymeric nature.
