    Abstract: A flowing junction reference electrode comprising a liquid junction member matched with a filter. The junction member and the filter are situated between a reference electrolyte solution and a sample solution. An array of nanochannels spans the junction member and provides fluid communication between the electrolyte solution and the sample solution. The filter is configured to allow a greater flux of electrolyte than that associated with the junction member. Preferably, the number of pores is greater than the number of nanochannels. The filter is preferably configured to have pores with an inner diameter that is the same or less than the inner diameter of the nanochannels. In some embodiment, the resistance of the filter is made lower relative to the resistance of the junction member by selecting suitable length, number, and inner diameter size for the pores of the filter relative to the nanochannels of the junction member.

  • Publication number: 20140332399
    Abstract: A Low Capacity Sodium Hypochlorite Generation (LCHG) system uses batching rather than the conventional continuous flow method in the production of sodium hypochlorite. Batching eliminates the need for metering pumps for brine and dilution water, as well as their associated controls and maintenance/servicing demands. Batching also precisely controls the ratio of brine to dilution water in the electrolyzer to produce a consistent strength sodium hypochlorite solution. Consequently, the LCHG system has fewer components, greater reliability and simpler maintenance than the continuous-flow on-site electrolytic chlorination systems.

A high surface area skeletal metal catalyst material such as Raney Nickel can be used as the cathode. Electrocatalytic hydrogenation and/or hydrodeoxygenation convert the organic substrates under mild conditions to reduce coke formation and catalyst deactivation. The process converts oxygen-containing functionalities and unsaturated bonds into chemically reduced forms with an increased hydrogen content.

  • Publication number: 20110100833
    Abstract: A method for producing chlorine dioxide with single-liquid electrolysis, wherein chlorine dioxide is generated by performing electrolysis by supplying a direct current to an electrolyte solution in a separating-membraneless electrolytic cell having a cathode and an anode, the method includes: (a) a step of generating chlorine dioxide by performing electrolysis by supplying the direct current to the electrolyte solution, which contains an alkali chloride, an alkali chlorite and a pH adjusting agent, wherein a pH of the electrolyte solution is 4 to 8; (b) a step of supplying a replenishing electrolyte solution, containing the alkali chloride, the alkali chlorite, and the pH adjusting agent, to the electrolytic cell during the electrolysis; and (c) a step of taking out the generated chlorine dioxide from the electrolyte solution.

  • Publication number: 20100230294
    Abstract: A method and solution for eluting one of antimony(V) and a mixture of antimony(III) and antimony(V) from an ion exchange resin, comprises contacting the resin with an eluting solution comprising thiourea having a concentration of at least 0.002 M and hydrochloric acid having a concentration of at least 3 M. The method can be used for electrolytes in an industrial electrorefining process, by the further steps of contacting the electrolyte with an ion exchange resin to adsorb the antimony from the electrolyte and separating the resin from the electrolyte, before contacting the resin with the eluting solution comprising thiourea and hydrochloric acid. The method and solution address the difficulties of removing antimony(V), and allow for increased reuse of the resins.

  • Publication number: 20100193369
    Abstract: Systems, methods and apparatus for facilitating removal of molten metal from an electrolysis cell are provided. In one embodiment, a system includes a container and an electrical source coupled to the container. The electrical source may be configured to provide complementary current to a spout of the container. This complementary current may create a complementary electromagnetic field at least proximal a tip portion of the spout. When the spout of the container receives the complementary current, and when the spout is in liquid communication with the molten liquid of the electrolysis cell, the complementary electromagnetic field of the complementary current may at least partially assist to increase the flow of molten metal into the spout of the container.
