ASTM E1771-07 Determination of Copper in Anode and Blister Copper

Scope:

ASTM E1771-07 is a standard test method to evaluate the content of copper in commercial anode and blister copper. This method covers the necessary procedures to electrolytically determine the copper content.

Test Procedure:

After dissolution of the sample, the solution is evaporated to dryness and fumes are expelled by heat. The salt is dissolved in nitric acid, the solution is filtered, the acidity is adjusted, and the copper is electrolytically plated and weighed as the metal. 

Specimen size:

5.0 g of sample, measured to the nearest 0.1 mg is required for ASTM E1771-07 test method.

Data: 

The following equation can be used to calculate the percentage of copper,

where,

A = weight of cathode plus deposited copper, g,

B = weight of cathode, g,

C = copper found, g, and

D = sample used, g.

Conclusion:

ASTM E1771-07 helps in determining the amount of copper in commercial copper and blister copper.
