Abstract
Recently introduced novel voltammetric and chronoamperometric techniques, derived from square-wave voltammetry (SWV), are being studied for their analytical utility. Three voltammetric protocols, namely potential-corrected, multi-sampled, and cumulative square-wave voltammetry, along with square-wave chronoamperometry (also known as electrochemical Faradaic spectroscopy), are described and analytically tested. The evaluation is based on both theoretical and empirical approaches, including statistical evaluation and comparison with standard electrochemical techniques such as differential pulse, conventional SWV, and conventional chronoamperometry. The novel techniques exhibit improved analytical performance compared to standard electrochemical measurements, providing a basis for advanced analysis and analytical applications.
