Research Areas: Analytical and Environmental Chemistry

Our group studies the origin, fate, transport, and remediation of inorganic contaminants in soil and groundwater environments.  We focus on the solution and surface chemistry of redox-sensitive elements such As(III)/(V), Cr(III)/(V), Se(IV)/(VI) and the analytical speciation of these elements in complex matrices such as soil, sediment, and wastewater. Specific topics include:

Environmental Remediation: Development and characterization of sorbents such as synthetic metal oxides and metal oxide-coated substrates, nanoscale silver and zero-valent iron, and supported zero-valent iron for removal of metal cation (Pb(II), Cd(II), Zn(II)) and anion (As(V), Cr(VI), Se(VI)) contaminants. Heterogeneous reactions of redox-sensitive elements such as As, Cr, and Se at natural mineral surfaces.

Environmental remediation examples

Chemical Analysis: Separation and detection of redox sensitive elements (As(III)/As(V), Se(IV)/Se(VI) and Cr(III)/Cr(VI)) by hyphenated techniques such as ion chromatography coupled with AA, ICP or ICP-MS spectrometry. Detection of trace elements using UV-VIS, graphite-furnace electrothermal AA and MP-AES spectrometry. Elemental analysis by X-ray fluorescence (XRF).

Chemical Analysis examples

Spectroscopy: Applications of X-ray absorption spectroscopy (EXAFS and XANES) and X-ray photoelectron spectroscopy (XPS) for elucidation of the structure of metal cation and oxyanion surface complexes on synthetic materials (nanomaterials, metal surfaces, metal oxides) and natural minerals found in soil and groundwater aquifers.

Spectroscopy examples

Microscopy and Particle Analysis: Applications of scanning electron microscopy (SEM) for surface analysis of minerals and nanoparticle imaging and use of energy dispersive analysis of X-rays (EDX) for elemental analysis of materials. Analysis of synthetic nanoparticles, metal oxides and natural soil and sediment minerals by X-ray diffraction, BET N2 and EGME methods and electrophoretic mobility.

Microscopy and Particle Analysis examples

Chemical Modeling: Chemical modeling of redox speciation, precipitation, and adsorption reaction constants in environmental systems using PHREEQC, GEOCHEM, MINTEQ, and FITEQL.
