How to wash away chloride ions from copper oxide
Thread Content
The raw material is copper chloride, and the final product is copper oxide. What methods or equipment should be used for washing in order to reduce chloride ions to below 300 ppm? It would be best if it has industrial applications. Thank you all in advance

If chemical methods are used to remove chloride ions, metal ions that can form precipitates with chloride ions must be employed; for example, if soluble lead salts are used, lead chloride causes severe environmental pollution, and fines will be imposed once this is detected by environmental authorities. The best method is electrolysis using direct current, as it makes it easy to remove chloride ions. However, it is important to be aware of the high toxicity of chlorine gas and to take care in its collection.
