The invention relates to an electrode arrangement () for electrochemically treating a liquid. The electrode arrangement () has two electrodes (), each of which has at least one electrode surface () and at least one through-flow chamber () with at least one inlet () and at least one outlet (). The at least one through-flow chamber () is delimited on at least one first face by at least one electrode () which has a structure () on its electrode surface () such that a distance between the electrode surface () and a second through-flow chamber () face lying opposite the first face is varied. The invention is characterized in that the structure () forms at least 30% of the electrode surface () and is designed such that the distance between the electrode surface () and the second face increases and decreases multiple times along at least one direction, and the liquid flowing through the through-flow chamber () is mixed by means of the structure () and is set into a turbulent flow in particular.

The invention relates to a method for electrochemically producing electrolyzed water in an electrode arrangement () which has an anode chamber and a cathode chamber that are separated by an ion-selective membrane (). The anode chamber is delimited on at least one side by at least one anode (), and the cathode chamber is delimited on at least one side by at least one cathode (). In the method: a) water, in particular distilled water or ultra purified water, in which an electrolyte is located, is conducted through the anode chamber, b) water, in particular distilled water or ultra purified water, is conducted through the cathode chamber, c) the water, in particular the distilled water or the ultra-purified water, is mixed and in particular set into a turbulent flow in the anode chamber and/or cathode chamber, and d) an electric voltage is applied to the anode and the cathode such that electrolyzed water is produced in the cathode chamber.

Method for electrochemically producing electrolyzed water

A diamond layer can be applied stably onto a graphite substrate in a CVD process when the graphite substrate is subjected to the following pretreatment steps before the CVD process:

Method for applying a diamond layer onto a graphite substrate

Diamond electrodes with improved adhesion of the diamond layer to the electrode are produced by sandblasting a surface of the electrode body, and then non-oxidatively etching the roughened (sandblasted) surface so as to remove at least 5 &#x3bc;m of material from under the roughened surface. By removing at least 5 &#x3bc;m of material, the sand particulates in the surface of the electrode body are eliminated, and damage in the form of cracks in the electrode body which result from sandblasting is reduced or eliminated, and further, a surface metal oxide coating is not created. All of these contribute to preparing a surface where spalling of the diamond layer is less likely to occur. Concentrated phosphoric acid is an exemplary non-oxidative etchant used in the process.

Diamond electrode and process for producing it

The invention relates to an electrode assembly for the electrochemical treatment of liquids with a low conductivity. Said assembly comprises electrodes (), between which a polymer solid electrolyte () is situated. The electrodes are pressed against one another by means of a compression device () and are configured in such a way that the assembly can be traversed by the liquid. To produce said assembly simply and to ensure that it is flexible and easy to use, the compression device () is supported on the electrodes ().
