Groundwater
Environmental Chemistry Research at UCF

Environmental research pertaining to air, water, and soil pollution, remediation, and characterization. Pesticide breakdown and interactive products and the effects of population growth on previously undisturbed environments.

Oxidized 100-Mesh - US Impact:

Platelet-type structures, underlying surface obscured (L) Sonication removes platelets, cracks smooth surface (R)

GW Soaked Filings - US Impact:

Obvious debris after several months in groundwater (L) After sonication, surface looks similar to acid-washed material (R)

Exposed to TCE for 90 days:

Obvious debris after 90 days in saturated, aqueous TCE (L) After sonication, less surface debris (R)

Emulsion:

This drawing depicts what we envisioned before the research began… Emulsion composition: corn or vegetable oil, small amount of food-grade surfactant, and iron particles

Iron Emulsion Droplet:

This is a micrograph of a nanoscale iron emulsion droplet!! Woo Hoo! This emulsion droplet is approximately 12 microns in diameter.

SEM of Nanoscale Iron:

Magnification = 20000X

Oxidized Filings - US Impact:

Various structures on surface: rosettes, filaments, platelets (L) Sonication removes structures, cracks smooth surface (R)
