报告题目：Chromate Reductive Immobilization for Site Remediation
Dr. Baolin Dengis Chair Professor in Environmental Engineering at Southern University of Science and Technology. He is currently on leave from the University of Missouri where he is LaPierre Professor in the Department of Civil & Environmental Engineering. Deng’s research concerns with drinking water treatment, wastewater treatment and reuse, membrane fabrication and application, and important environmental process kinetics and mechanisms relevant to contaminated site remediation. He has been PI/co-PI for over three dozen research projects including the CAREER award from the National Science Foundation. He published over 100 peer-reviewed journal articles and book chapters with >5000 citation and H-index 38 (Google Scholar). Deng has served on the EPA Science Advisory Board Drinking Water Committee, and is the Asian Regional Editor forEnvironmental Engineering Science.
This presentation will explore how the redox transformation of chromium can be applied for the site remediation. Cr(VI) species are more toxic and mobile than the Cr(III) species, thus Cr(VI) reduction has been used as an important approach for the contaminated site remediation. Kinetics and mechanism of Cr(VI) reduction by hydrogen sulfide and iron sulfide are and potential Cr(III) oxidation was examined.
