Then, the gold electrode was electrochemically cleaned by cycling from − 0.2 to 1.6 V (vs. Ag/AgCl) at a scan rate of 100 mV/s in 0.5 M sulfuric acid until the CV peaks became stable (40 cycles). Subsequently, the gold electrode was rinsed with water, dried with nitrogen and inserted into the electrochemical cell.

the filtered gold from that reaction gets mixed with with hcl and nitiric acid after that, we precipitate to make the gold into a solid again (dust) -- i believe i skipped mixing the gold with HCL and Nitric acid and just added sodium metabisulfate and urea. is it possible to take that step back to add the HCL and nitric acid lol..
