    摘要： A bipolar system electrolytic cell having a partition wall made of explosion-bonded titanium plate and iron plate which is electrically connected to anode of titanium substrate at its titanium side and to cathode of iron at its iron side, space is preferably given between anode and the partition wall and also between cathode and the partition wall. An assembly having a number of such unit cells arranged in series is useful for electrolysis of sodium chloride which can be performed under a low voltage per unit cell.

    摘要： In an electrolytic cell having cation exchange membrane as diaphragm to partition said cell into cathode and anode chambers, electrolysis of an electrolyte aqueous solution is conducted while generating gas from anode by keeping the inner pressure in cathode chamber higher than that in anode chamber. Some disadvantages caused in the case of electrolyzing an aqueous alkali metal halide solution to form alkali metal hydroxide in cathode chamber are overcome by adjusting the anolyte at pH

    摘要： High purity aqueous alkali hydroxide solutions containing predetermined, low concentrations of alkali metal halide are obtained in the anode compartment of an electrolytic cell using a cationic ion exchange membrane by conducting the electrolysis under controlled conditions such that the difference between the concentration of alkali metal halide in the anode compartment and the limiting concentration of alkali metal halide in the anode compartment is within a defined range.

    摘要： A multi-cell electrolyzer comprising a plurality of unit cells, each of which is composed of an anode chamber containing an anode and a cathode chamber containing a cathode and a cation exchange membrane for partitioning said unit cell into said anode chamber and said cathode chamber, and each of which is adapted to have an internal pressure maintained at a level higher than the atmospheric pressure in operation of the electrolyzer, said plurality of unit cells being arranged in series and adapted to be energized through a plurality of current lead plates, and rigid multi-contact electrically conductive means provided between the adjacent unit cells and/or between each current lead plate and the unit cell adjacent thereto, thereby establishing electrical connection between the adjacent unit cells and/or between each current lead plate and the unit cell adjacent thereto. With such a structure, not only is the electrical contact resistance between the adjacent unit cells and between each current lead plate and the unit cell adjacent thereto extremely reduced but also the current density in the unit cells is rendered uniform. Further, the present multi-cell electrolyzer can be easily constructed either in a bipolar form or in a monopolar form using unit cells common to both of the bipolar and monopolar forms.

    摘要： A method of simultaneously obtaining separate enriched fractions of heavier and lighter isotopes from mixtures thereof with the use of an ion exchange resin column by passing a ligand body containing this isotope mixture through the column. The isotopes, as they are passed through the column, are present in the forms of ligand-containing coordination compounds having different valence states and are followed by an eluant and form a band which travels through the column, the front and rear portions of which are respectively enriched in one of the isotopes and depleted in the other.
