The Wohlwill process is an industrial-scale chemical procedure used to refine gold to the highest degree of purity (99.999%). [1] The process was invented in 1874 by Emil Wohlwill . This electrochemical process involves using a cast gold ingot , often called a doré bar , of 95%+ gold to serve as an anode .
Invented by Emil Wohlwill in 1874, the Wohlwill process produces the highest purity gold (99.999%). It is an electrolytic process using pure gold for the cathode (or titanium as a starter cathode) and chloroauric acid (gold chloride-hydrochloric acid) as the electrolyte; this is made by dissolving gold with chlorine gas in the presence of ...
The resulting gold is 99.5% pure, but of lower purity than gold produced by the other common refining method, the Wohlwill process, which produces gold of up to 99.999% purity. [1] [2] The Wohlwill process is commonly used for producing high-purity gold, such as in electronics work, where exacting standards of purity are required.

A typical electrode gel consists of a mixture of water, a thickener such as polyvinyl alcohol or carboxymethyl cellulose, and an electrolyte to increase conductivity. [1] [2] Some electrode gels have been shown to pose a potential fire risk when high-energy pulses are used, as for example when defibrillators are used. [3]

A typical elastic modulus for a gel polymer electrolyte is 10 MPa, which is two orders of magnitude below that of a typical liquid electrolyte. [14] Gel polymer electrolytes also shown specific applications for lithium-ion batteries to replace current organic liquid electrolytes. This type of electrolyte has also been shown to be able to be ...
