Miscellaneous. Hydrochloric acid is used for the recovery of semiprecious metals from used catalysts, as a catalyst in synthesis, for catalyst regeneration (see Catalysts, regeneration), and for pH control (see Hydrogen-ION activity), regeneration of ion-exchange (qv) resins used in wastewater treatment, electric utiUties, and for neutralization of alkaline products or waste materials. In addition, hydrochloric acid is also utilized in many production processes for organic and inorganic chemicals.

Aqueous systems have been used in separations, coatings, and synthesis. Aqueous biphasic systems have been developed for hquid-liquid extractions using water-soluble polymers such as polyethylene glycol, and inorganic salts such as ammonium chloride or potassium phosphate (Rogers et al., 1998), (Sherman et al., 1998). These systems have been investigated for use in the separation and recovery of heavy metals from mixed wastes and in the recovery of colored impurities from textile waste streams (Sherman et al., 1998). 

In 1963 Dr. Danbk joined the Institute of Inorganic Chemistry of the Slovak Academy of Sciences in Bratislava, of which he was the director in the period 1991-1995. His main field of interest was the physical chemistry of molten salts systems in particular the study of the relations between the composition, properties, and structure of inorganic melts. He developed a method to measure the electrical conductivity of molten fluorides. He proposed the thermodynamic model of silicate melts and applied it to a number of two- and three-component silicate systems. He also developed the dissociation model of molten salts mixtures and applied it to different types of inorganic systems. More recently his work was in the field of chemical synthesis of double oxides from fused salts and the investigation of the physicochemical properties of molten systems of interest as electrolytes for the electrochemical deposition of metals from natural minerals, molybdenum, the synthesis of transition metal borides, and for aluminium production.

Molten salts (called fluxes) and also water at high pressures and temperatures are excellent solvents for many inorganic solid compounds. Inorganic synthesis from flux is discussed in Section 8.3.2, while water as a solvent for synthesis of oxides under hydrothermal conditions is the subject of Section 8.3.3. Colloidal methods are of increasing importance and the synthesis of mixed oxides by polymerization of hydrolized metal-organic molecules is the fourth subject in the group of synthesis from liquids. 

There is no evidence for the synthesis of organomercury compounds in mammalian tissues. The possibility of methylation of inorganic or metallic mercury by oral or intestinal bacteria has been discussed but not proven [28,29]. From several investigations on brains from victims of acute and chronic methylmercury intoxications in Japan [30,31] it can be concluded that in the brain methylmercury is partly biotransformed with time to inorganic mercury.
