The role of different soil sample digestion methods on

The measurement of trace-element concentration in soil sediment and waste is generally a combination of a digestion procedure for dissolution of elements and a subsequent measurement of the dissolved elements. “Partial” and “total” digestion methods can be used in environmental monitoring activities. To compare measurement results obtained by different methods it is crucial to

Large Scale Gold Refining By the Aqua Regia Acid Method

Enough aqua-regia must be added to dissolve all of the gold however the excess aqua-regia that is required to accomplish this will later have to be removed so large excesses should be avoided. Toward the last the reaction is much slower and it is desirable to warm the solution and to agitate it regularly but the aqua-regia should not be heated to boiling.

Aqua regia - Wikipedia

Aqua regia dissolves gold though neither constituent acid will do so alone because in combination each acid performs a different task.Nitric acid is a powerful oxidizer which will actually dissolve a virtually undetectable amount of gold forming gold ions (Au 3+).The hydrochloric acid provides a ready supply of chloride ions (Cl −) which react with the gold ions to produce
