Capture of Chlorine Gas

Post by JosephMSME »

I am looking for a simple way to neutralize or capture small amounts of chlorine gas that are produced in my set-up.  I am trying to take time-lapse video of the growth of nickel dendrites during electroplating of nickel from a nickel chloride solution.  I am using nickel chloride because I already happen to have a ready supply of it and I am working with a limited budget.  Ventilation of the gas out of the building is not really practical for a number of reasons, so I am exploring any capture or neutralization options that do not produce any large exothermic or violent reactions and will not add significantly to the cost of my set-up. Thanks, Joe

Take Nickel anodes. Then no chlorine will developed.

Thank you. That is great. However, I did use a pure nickel anode and saw bubbles being produced at the plating site. I assumed this was chlorine being generated. If that is not the case, can you tell me what these bubbles are? Thanks again.

On cathode side hydrogen is developed, if voltage to high. Chlorine will be developed on anode side, if carbon, ülatinum or pther inert material is used.

Then I must have been electrolyzing the water in my solution. I really appreciate your help. Thanks again.

Yes that is the case, probably to high current.
