Practical methods: steps involved in voltammetry:

1.         Sample treatment: For this analysis the sample must be in a solution form. If solid, it has to be brought within solution through dissolving in an appropriate solvent. Liquids or solids along with low solubility are to be digested or extracted.

2.         Addition of supporting electrolyte: Every analysis has to be performed using an appropriate supporting electrolyte, of appropriate concentration generally at least 10 times the concentration of the analyte.

3.         Bubbling of the solution with N₂.

4.         Electrode cleaning.

5.         Addition of the standard analyte.

6.         Scanning/registration of voltammograms.

7.         Measurement of peak height.

8.         Drawing of the graphs.

9.         Calculation of the unknown concentration.
