Lecturer in Environmental Engineering

Background

Anke Neumann is an environmental chemist with great interest in redox processes at the mineral-water interface and how these processes affect the fate of organic and inorganic compounds in the environment. In her PhD, she studied how Fe-bearing clay minerals reduce different types of organic contaminants (chlorinated hydrocarbons, nitroaromatic compounds) and then moved on to elucidate how Fe-bearing minerals become redox-activated in the reaction with dissolved Fe(II). In a 2-year project in Bangladesh, she investigated redox reactions and Fe mineral phase transformations in iron-containing filters, which remove arsenic from drinking water. To facilitate her research, she has been applying a variety of techniques to analyze organic compounds and inorganic species in aqueous phase, to characterize mineral phases, and has been using stable isotopes as process tracers. Working at the interface of environmental engineering, soil science, and (bio)geochemistry, she is eager to address emerging and transdisciplinary questions related to water sustainability.

Research Interests

My research focuses on redox processes at the mineral-water interface and how these processes impact water quality. My work spans the broad range from understanding fundamental mechanisms of electron transfer to application of redox processes for contaminant transformation or removal, both in natural and engineered environments. Working at the interface of environmental engineering, soil science, and (bio)geochemistry, I am eager to address emerging and transdisciplinary questions related to water sustainability.

My current specific research interests include

* redox reactions in complex biogeochemical environments;

* effects of fluctuating redox conditions on Fe mineral reactivity;

* implications of Fe(II)-induced processes at minerals for contaminant transformation.


To address these research themes, she uses a variety of techniques to analyze organic and inorganic species in aqueous phase (HPLC, GC-MS, GC-FID, ICP-MS), to characterize mineral phases (infrared spectroscopy - ATR-IR, DRIFT, X-ray diffraction - XRD, Mössbauer spectroscopy, electron microscopy - SEM, TEM), and stable isotopes as process tracers.
