I can not seem to find much research about the topic, so if anyone has done some research on the topic I would greatly appreciate advice. Thank you.
This article mentioned the use of NaOH and Na2SO4 as a catalyst in the dissolution of Al in a OH solvent. I have however not tested it myself yet.
"Anodic Dissolution of Pure Aluminum during Electrocoagulation Process: Influence of Supporting Electrolyte, Initial pH, and Current Density. Ind. Eng. Chem. Res. 2011, 50, 23, 13362–13372"
I will follow this thread with great interest.
An well known way is the generation of local elements on the aluminium surface.
The aluminium gritty or foil is to be contacted with a solution of copper sulfate or silver nitrate or mercuric nitrate for some minutes with PH lower 4. Than you wash it with distilled water and add the NaOH.
best regards
Hello Hermann, thank you for the answer. I will definitely try your solution. Do you have some literature for further reading?
Excuse me,please, but it is more or less basic knowledge.
look for instance
:Heinrich Remy: Lehrbuch der Anorganischen Chemie. Band I und II, Akademische Verlagsgesellschaft Geest & Portig, 12. und 13. Aufl. Leipzig 1973
BUT a small correction of my previous text: PH of the metal solution should be lower then 2.
