By a News Reporter-Staff News Editor at Ecology, Environment & Conservation -- Fresh data on Science - Environmental Science and Technology are presented in a new report. According to news reporting originating in Shanghai, People’s Republic of China, by VerticalNews journalists, research stated, “Sulfidation has gained increasing interest in recent years for improving the sequestration of contaminants by zerovalent iron (ZVI). In view of the bright prospects of the sulfidated ZVI (S-ZVI), this review comprehensively summarized the latest developments in sulfidation of ZVI, particularly that of nanoscale ZVI (S-nZVI).”
Financial supporters for this research include Ministry of Education of the People’s Republic of China, China Postdoctoral Science Foundation, National Natural Science Foundation of China, Tongji University, Natural Science Foundation of Zhejiang Province, State Key Laboratory of Pollution Control and Resource Reuse.
The news reporters obtained a quote from the research, “The milestones in development of S-ZVI technology including its background, enlightenment, synthesis, characterization, water remediation and treatment, etc., are summarized. Under most circumstances, sulfidation can enhance the sequestration of various organic compounds and metal(loid)s by ZVI to various extents. In particular, the reactivity of S-ZVI toward contaminants is strongly dependent on S/Fe molar ratio, sulfidation method, and solution chemistry. Additionally, sulfidation can improve the selectivity of ZVI toward targeted over water under anaerobic conditions. The mechanisms of sulfidation-induced improvement in contaminants sequestration by ZVI are also summarized.”
According to the news reporters, the research concluded: “Finally, this review identifies the current knowledge gaps and future research needs of S-ZVI for environmental application.”
