    摘要: A process for the production of hydrogen peroxide solution from seawater as a starting material substantially free of effective chlorine or organic halogen compounds. An electric current is passed through an insoluble anode and an oxygen gas diffusion cathode while keeping the halide ion concentration of anolyte supplied to the anode chamber to a level not greater than 1 g/l. Hydrogen peroxide thus generated dissolves in the catholyte. Anodic oxidation of halide ions is suppressed, to thereby inhibit the production of effective chlorine.

    摘要: An electrolytic electrode substrate comprises an electrically conductive substrate and, formed on the surface of the electrically conductive substrate, an oxide layer having a thickness of from 10 to 200 .mu.m, wherein the oxide in the oxide layer comprises a non-stoichiometric composition containing oxygen and at least one metal selected from the group consisting of titanium, tantalum, and niobium. An advantage of the electrode substrate is that it is stable when used in electrolytic processes involving a reversal of current flow. Further, the electrode substrate is stable in the presence of corrosive substances such as a fluorine.

    摘要: An electrolytic cell for obtaining a caustic alkali by closely contacting a gas diffusion electrode comprising a gas-liquid permeable metal substrate and a gas-liquid permeable collector connected to the substrate to a cation-exchange membrane while supplying an oxygen-containing gas from the opposite side of the cation-exchange membrane. Grooves for taking out a liquid containing a caustic alkali are formed in the contact surface of the gas diffusion electrode with the cation-exchange membrane. By the formation of the grooves, clogging of the perforations of the gas diffusion electrode with the caustic alkali so formed is prevented, whereby the gas supply can be smoothly carried out and the electrolysis can be stably carried out without reducing the cell voltage.

The device blocks sagittal bundles of rays. A preferred example of the supporting body is a cylindrical frame that holds the shading plates perpendicularly to the inner surface thereof. Alternatively, the shading planar members are formed within a lens element along the edge thereof.
