  1. Thank you for your reply. I put the capacitors in there because i just would like to absorb the ions onto the cotton board but avoid electrolysis of water appearing or chlorine gas production. Please let me know why it did not work even without the capacitors. Thanks.
  2. Dear All, I created a system as the pic showing as below: 1. 6 x 9-V batteries in series (54V) 2. 2 x capacitors (0.1 uF, 63V) 3. 2 x activated carbon cotton board electrodes (distance between the electrodes is 1 cm) 4. The solution is water with 1.3% table salt After connecting all wires, i put the electrodes in the solution, and hope the ions attached onto the electrodes, After 1 hour, I took the electrodes out of the solution, but I found the concentration of salt was still 1.3%. Please tell me what thing I did wrong. THX
