However, synthesis and manipulation with these extremely reactive/pyrophoric nZVI particles<br>represents a challenge and requires special precautions. In this study, we report a synthesis of S-nZVI from airstable<br>core-shell nZVI, which reactivity with contaminants and properties are comparable with the commonly<br>prepared S-nZVI particles (where the precursor was bare/pyrophoric nZVI particles). The undeniable novelty<br>dwells in the simplicity of the synthetic process, which ensures consequential safe and easy handling, manipulation,<br>and application of S-nZVI particles. This material, especially highly effective against halogenated organic<br>compounds and heavy metals, was characterized in detail and its advanced characteristics were evaluated in the<br>process of hexavalent chromium (Cr(VI)) reduction from model aqueous solutions and polluted groundwater.<br>The results offer valuable insights into the preparation of a novel nanomaterial with high application potential in<br>the effective degradation of heavy metals in polluted water. Overall, the novel way prepared S-nZVI particles,<br>designed for the potential large-scale production, eliminates the drawbacks of S-nZVI synthesized from bare nZVI<br>particles and offers the effective material suitable for any on-site application.</p>
