摘要： A metal hydroxide complex has a formula Me(OH)4*A−*nH2O or MeO2*A−*nH2O. Preferred complexes are formed in an alkaline medium, and particularly especially preferred anions include cyanide and cyanide gold complexes. Contemplated complexes are formed on a metal hydroxide (e.g., hydrated zirconium, hafnium, and titanium hydroxide), which may be disposed in a porous container. Consequently, contemplated compounds may be used in methods of reducing the concentration of an anion in an alkaline medium.

摘要： A protective element for an electrochemical accumulator is made of granular varistor material, the mean diameter of the grains of the varistor material being less than 1 .mu.m, in particular less than 250 nm and, for more than 60% of the grains of the varistor material, the grain size deviating by at most 40% from its statistical average. For the preparation of such grains, a dispersion is made up to form biochemical hollow bodies which have an internal diameter in accordance with the above requirements. The dispersion is admixed with salts which dissolve in the dispersion with the formation of intermediate ions of a substance forming an intermediate for a varistor material, the intermediate ion of a substance forming an intermediate for a varistor material being an intermediate ion of an element required for the varistor material or of a corresponding compound. The intermediate ions of a substance forming an intermediate for a varistor material are positioned in the enclosed void of the hollow bodies, being used to form the grains of the varistor material or an intermediate of corresponding shape, which are released by removing the sheath of the hollow bodies.

摘要： A process employing a fixed-resin bed Acid Retardation Unit (ARU) to separate spent acid from chlorine dioxide generators into a de-acidified sodium sulfate component and a purified sulfuric acid component. The de-acidified sodium sulfate produced is returned to the chemical recovery cycle of the kraft mill in place of acidic chlorine dioxide generator effluent thereby avoiding the destruction of alkalinity in pulp mill liquors. In addition, sulfuric acid is purified providing an opportunity for reuse in various mill applications, and/or concentrated and recycled to the generator. Alternatively, to avoid high evaporation costs, the purified acid can be used to regenerate a cation-exchange unit (CEU) used in the conversion of sodium chlorate to a sodium chlorate/chloric acid mixture which is fed to the generator in place of sodium chlorate and sulfuric acid. Using this approach, the sulfuric acid requirement of chlorine dioxide generators and, in turn, the amount of acidic generator effluent can be reduced. The process is applicable to both atmospheric and subatmospheric chlorine dioxide generators. In the latter case, the concentration of the purified sulfuric acid from the ARU or any other acid separation system can be increased by using a portion of it to dissolve the sodium sesquisulfate by-product from such generators.
