Electrochemical Detection of Nitrite on PANI-TiO/Pt Nanocomposite-Modified Carbon Paste Electrodes Using TOPSIS and Taguchi Methods.

Platinum nanoparticles are widely used in electrocatalysis and sensors. In this work, a novel modified carbon paste electrode based on PANI-TiO/Pt nanocomposites was developed electrochemically. To improve the performance of the PANI-TiO/Pt composite-modified electrode, a Taguchi orthogonal array was used for experimental design, and the best values of factors affecting the performance were determined using the technique for order preference by similarity to ideal solution (TOPSIS) and Taguchi optimization methods.
