The properties and efficacy of S-nZVI as a remediation agent in response to its preparation process and reaction conditions: a truth from meta-analysis

Abstract

The influence of the preparation process (including sulfurization method, sulfur reagents, and S/Fe molar ratio) and the reaction conditions of decontamination (pH value of the initial solution, reaction temperature, etc.)...

High-efficiency removal of Cd(ii) and As(iii) from irrigation water using a S–Fe–C composite: performance and mechanisms

“…The sulfidation of nZVI using agents like sodium sulfide or sodium thiosulfate yields S-nZVI, which is sought after for its increased reactivity and enhanced dispersibility in environmental remediation efforts. 22–24 The large amount of bagasse produced by the sugar industry around the world is seriously underutilized as a low-cost biological resource, resulting in significant waste and environmental pollution, which is not conducive to the sustainable development of agriculture, and there is an urgent need to explore new ways to maximize its resource value. Consequently, the development of composite materials that integrate biochar with S-nZVI is of significant practical interest.…”
