Definitions
- This invention relates to an electrode andparof percompounds by anodic oxidation.
- percompounds such as per-sulfuric acid, perboricacid, etc., and their salts
- platinum anodes must always be employed as all other metals do not permit of a deposit of the desired anion on the acid or its salt, such as $04 on sulfuric acid or a salt thereof, even though the metal might be sufliciently stable against attack by the electrolytic solution;
- the drawing shows a view in perspective of the improved anode.
- the anode of the present invention is formed of a central conducting core or rod- III of a common. metal, as, for instance, copper. Electrical contact and connection is made between rod- 10 and a conducting element H of metallic tantalum.
- a hard rubber sheath l2 formed with lips l3 which engage the tantalum member H.
- the anode is completed by connecting the platinum tip M to the tantalum member II.
- An anode for the production of percom- I pounds comprising a-core of conducting material, a sheathof non-conducting material stable toward the electrolyte of the bathin which the anode is used surrounding the corepa platinum tip'upon which nascent oxygen develops when the anode is used in the production of percompounds spaced from the sheath, and a memberof tantalum extending through the sheath and being co the platinum tip so that when in use no nascent oxygen-develops in contact with the sheath.
- An anode for the production of percom pounds comprising a core of copper, a sheath of non-conducting material surrounding "the cop- ,per core, a platinum tip spaced from the sheath and a member of tantalum extending through the sheath and having electrical contact with the core and the platinum tip so that when the anode I is used for the production of percompounds nascent oxygen'develops only upon the platinum tip and not in contact withthe sheath.
- an elongate elementof conducting material In an electrode, an elongate elementof conducting material, a second elongate elementoi electrochemically active conductingmlaterial ex-' tending parallel thereto and spaced therefrom, an insulating sheath surrounding said first element, and a plurality of electrochemically inactive conductors extending through said insulati ng sheath and between said two elements for maintaining rigid relation and for establishing electrical communication tlrierebetween.
- an elongate element of a .metallic conducting material a second elongate element comprising electrochemically active conducting tnaterial of platinum extending parallel to said first element and spaced therefrom, an insulating sheath surrounding said first element,
- the present invention provides an anode wherein a' ductors formed of tantalum and extending between laicl two elements for maintaining rigid relation and for establishing electrical communication therebetween.
