Polyoxometalate clusters embedded into hydrogel biobeads may be able to solve
the challenges posed by free proton generation during remediation of
trichloroethylene by acting as buffers and reducing protons to hydrogen gas. In
this thesis, the challenges posed by systems that contain both diffusion and
reaction processes for protons are considered mathematically, and a computer
simulation to was developed to prove the relationship between diaphragm cell lag
period and reactive capabilities of …

Trichloroethylene (TCE), a toxic and carcinogenic contaminant, presents unique
challenges for cleanup because of its water solubility, density, and volatility.
Bioremediation of TCE is a promising cleanup method; however, metabolism of TCE
results in acid generation that inhibits remediating microorganisms. Calcium
alginate(CA)-polyvinylalcohol (PVA) hydrogels show promise for protecting
remediating microbes, however diffusion of TCE or its byproducts through these
polymers is unknown. To …
