Abstract

This chapter provides an overview of employing weak magnetic field (WMF) and premagnetization to improve the reactivity of ZVI toward various metal (loid)s. The rate constants of metal(loid)s sequestration by ZVI were increased by 1.1-383.7-and 1.2-12.2-fold due to the application of WMF and premagnetization, respectively. The mechanisms of WMF-induced improvement in contaminant sequestration by ZVI are also summarized. Finally, this chapter identifies the current knowledge gaps and future research needs of WMF/ZVI system for environmental application.
