摘要:
The present invention relates to a composition including a ²-type iron silicate, which includes all or part of iron in a ²-type framework structure, and a solid acidic porous inorganic oxide. The present invention is characterized in that the ²-type iron silicate is compounded with the porous inorganic oxide having solid acidic properties so that the solid acidic function derived from aluminum of the ²-type iron silicate, is reinforced or complemented by the porous inorganic oxide, the individual particles of which are physically isolated from each other. It is preferred that the fluorine content relative to the dry weight of the ²-type iron silicate is 400 ppm or less and the crystal particles of the ²-type iron silicate have a truncated square bipyramidal morphology. According to the present invention, a composition that is useful as a high-performance catalyst, adsorbent, or the like, can be provided.

[Problem] To provide a so-called competitive immunological assay method capable of more uniformly immobilizing on a solid phase a substance equivalent to an antigen. [Solution] This immunological assay method measures an analyte substance in a sample by using: an equivalent substance immobilized on the solid phase during the execution of the assay, the equivalent substance being immunologically equivalent to the analyte substance; and a labeled antibody for specifically binding to the substance equivalent to the analyte substance. The assay method is characterized in that the equivalent substance is immobilized on the solid phase using: a bond between the equivalent substance and a carrier substance, the carrier substance being a substance to which the labeled antibody does not bind; and a bond between the carrier substance and a specific binding substance immobilized on the solid phase, the specific binding substance being a substance that binds specifically to the carrier substance.

The invention provides electrolytic a manganese dioxide with a BET specific surface area of 20 to 60 m 2 /g, and a volume of at least 0.023 cm 3 /g for pores with pore diameters of 2 to 200 nm. Also provided is a method for producing an electrolytic manganese dioxide including a step of suspending a manganese oxide in a sulfuric acid-manganese sulfate mixed solution to obtain the electrolytic manganese dioxide, wherein a manganese oxide particles are continuously mixed with a sulfuric acid-manganese sulfate mixed solution, for a manganese oxide particle concentration of 5 to 200 mg/L in the sulfuric acid-manganese sulfate mixed solution. Still further provided is a method for producing a lithium-manganese complex oxide, including a step of mixing the electrolytic manganese dioxide with a lithium compound and heat treating the mixture to obtain a lithium-manganese complex oxide.
