| dc.description.abstract | Electrochemistry, a field revolving around charge transport, is omnipresent in our every-day life.
It is found in batteries, water treatment, medicine, and food processing, to name a few. Water
dissolves more substances than any other liquid and is consequently easily polluted. Self-evidently,
drinking water quality is crucial to our health. Water disinfection refers to any process that removes
pathogens from drinking water. Electrochemical treatments are one of the processes used for water
disinfection and are advantageous wherewith required chemicals are formed in situ, while needing
less and in some cases no other additional chemicals. Porous electrodes are becoming increasingly
prevalent in electrochemical systems due to enhanced features such as reaction kinetics and mass
transport. The arising complexity of the electrochemical processes at the pore-scale, involving
multicomponent reactive flow, poses numerous challenges to the currently available experimental
methods and the macro-continuum mathematical models. This work is aimed at the development
of pore-scale numerical model using the Lattice Boltzmann Method and focuses on anodic
oxidation under the aqueous condition. Historically, iodine has been used as a disinfectant for
wounds as well as water. Excess consumption however can have adverse health effects such as
thyroid disease. Using potassium iodide for water disinfection allows for iodine to be produced
via anodic oxidation and then consumed through cathodic reduction. The relationship between
concentrations, flow rates and potentials are investigated in a flow-through porous electrode. [...] | en_US |
