Enhanced electrocatalytic reduction of hexavalent chromium with reduced pH dependence <i>via</i> alternating potential polarization using a polyaniline–chitosan composite electrode
The slow kinetics and strong pH dependence of hexavalent chromium, Cr(VI), electroreduction pose significant challenges for efficient remediation. Herein, an innovative alternating potential technique coupled with a polyaniline/chitosan composite electrode is developed to achieve rapid Cr(VI) removal (up to 17.8 h<sup>-1</sup> at pH ∼ 2.0) while mitigating pH sensitivity (1.2 h<sup>-1</sup> at pH ∼ 5.0).
