The assay for monitoring the content of sulfite ions (SO32−) is essentially important because sulfite has some seriously toxic effects on both environment and human health. For this, a SO32- electrochemical sensor was fabricated utilizing molybdenum disulfide (MoS2) and Nafion. The cyclic voltammetry (CV) and differential pulse voltammetry (DPV) showed that MoS2 had excellently catalytical activity for the redox of SO32-....
