Good afternoon I don’t know what topic you are writing your master’s thesis on, so I can suggest reading these articles:
Borrill A. J., Reily N. E., Macpherson J. V. Addressing the practicalities of anodic stripping voltammetry for heavy metal detection: a tutorial review //Analyst. – 2019. – Т. 144. – №. 23. – С. 6834-6849.
Elgrishi N. et al. A practical beginner’s guide to cyclic voltammetry //Journal of chemical education. – 2018. – Т. 95. – №. 2. – С. 197-206.
