Wohlwill process lower purity gold is required refiners often utilize the Miller process due to its relative ease, quicker turnaround times, and because it does not require a large inventory of gold, in the form of chloroauric acid, on site at all times. Wohlwill process The Wohlwill process is an industrial-scale chemical procedure used to refine gold to the highest degree of purity (99.999%). 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. Lower percentages of gold in the anode
Industrial enyzmes medium, mild isolation conditions must be used. Depending on the intended use of the enzyme, different levels purity are required. For example, enzymes used for diagnostic purposes must be separated to a higher purity than bulk industrial enzymes to prevent catalytic activity that provides erroneous results. Enzymes used for therapeutic purposes typically require the most rigorous separation. Most commonly, a combination of chromatography steps is employed for separation. The purified enzymes are either sold in pure form and sold to other industries, or added to consumer goods. Industrial enyzmes Industrial enzymes are enzymes that are commercially used in a variety
