Faraday law examination

2004

Dear company,

I am a M.S student in chemistry facing with a problem that I hope help me. Since two months ago, I work on gold refinery ,but time of this process doesn't obey Faraday's Law and it consumes time 70 times greater. also I can't remove nitric acid interference at cathode and after passing 30 seconds my process doesn't go on.

Best regards

You haven't described your process/experiment, Mr. Safdari, so it is very difficult to guess why it doesn't work. However, you cannot plate ions out of a solution which are not dissolved in that solution, so my first guess would be that there is little gold in solution.

You may be correct that the oxidizing power of nitric acid is fighting your attempt to reduce gold onto the cathode.
