Abstract

Electrochemical measurements (EMs) are utilized on corrosion studies and electrochemistry applications. Corrosion is a naturally occurring phenomenon, and that negatively affect functionality of engineering components. To prevent and mitigate it, EMs such as Open circuit potential (OCP), Potentiodynamic Polarization (PDP) and Electrochemical Impedance Spectroscope (EIS) are carried out. Details on all EMs which are carried out to characterize corrosion are included in this study. As twenty-first century industrialization grows, production of inks and dyes for various industrial also grow in direct proportional order. From eventual usage of products manufactured with inks and dyes, different elements become present in wastewater. This phenomenon consists risk to human being, plant and animals. Hence, EMs is necessitated to remove pollutants from the wastewater. On a quite number of EMs, photoelectrochemical technique (PET) is worthwhile on disintegration of havoc in wastewater. PET is carried out within an electrochemical cell (EC). In demonstration of the EMs impact, materials which are used as anodes (photoanodes) within the EC and the engaged organic pollutant simulating solution are thoroughly profiled before and after EMs. All undertakings give necessary information needed on degradation of organic pollutants from the wastewater. Hence, this chapter explains the following important aspects on Electrochemistry application: (i) PET technique significance and its functionality which make it supersedes other techniques. (ii) A standard EC operation and the constituents elements for successful degradation of wastewater. (iii) Pre and post-measurements techniques which are used as underpinnings demonstrating effectiveness of EMs. (iv) Overall, significance of engaging EMs on wastewater treatment. Graphical Abstract: Corrosion is a tendency of metallic materials returning back to their original states. Therefore; the electrochemistry is a study of electrons migration during metallic substrates application. This shows Corrosion and electrochemistry involve same techniques, but different interpretations.
