Inorganic complexes geochemistry

Wood, S.A. (1990a) The aqueous geochemistry of the rare-earth elements and yttrium. 1. Review of available low-temperature data for inorganic complexes and the inorganic REE speciation of natural waters. Chem. Geol., 82, 159-186. 

The next chapter will discuss the nature of energy and the ways in which it can be incorporated into chemicals using the basic principles of chemistry and geochemistry set out in Chapters 1 and 2 so as to create what we know as a system called life locked into the environment, the total ecosystem. (Note Heat is given out in small amounts even in the forward step but we shall ignore it here and elsewhere.) Importantly notice that equilibria limit the diversity of particularly inorganic compounds and complexes but are not usually relevant to the discussion of the properties... 

The isotope geochemistry of Se is complex because it involves several inorganic oxidation states and organic forms, kinetic isotope effects, and microbial action (Fig. 3). Fortunately,... 

This volume covers ongoing research and, thus, leaves many questions unanswered and many problems unsolved. The geochemistry of disposed radioactive wastes involves many complex issues that will require years of additional research to resolve. High-priority problems include integration of geochemical data with computer models of chemical interaction and transport, definition of environmental conditions that affect the behavior of radionuclides at specific disposal sites, evaluation of complex formation of dissolved radionuclides with inorganic and organic complexants, and determination of radionuclide solubilities in natural waters. 

Despite of applications in geochemistry and in crystal growth long before, the hydrothermal technique has only recently been exploited in the routine preparation of inorganic materials. Nevertheless, hydrothermal and related syntheses have evolved into an area of rapidly increasing importance for the preparation of new and structurally complex solid-state compounds [15-18]. It was only during the last two decades that borates synthesized by utilizing hydrothermal and related techniques have occasionally been reported [19,20].
