Rapid Oxidative Dissolution of Zerovalent Iron Induced by Sulfite for Efficient Removal of Arsenate and Arsenite: Selective Formation of Scorodite

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: 58(36), P. 16225 - 16235

Published: Aug. 27, 2024

In this study, we proposed a moderate oxidation strategy for accelerating the oxidative dissolution of zerovalent iron (ZVI) using sulfite (S(IV)), thereby improving removal As(V) and As(III). Results revealed that, in presence 2.0 mM S(IV), both As(III) were selectively converted into scorodite at pH
