Mathematical modelling of quantum yield enhancements of methyl orange photooxidation in aqueous TiO2 suspensions under controlled periodic UV LED illumination

- Photooxidation of methyl orange under periodic illumination in UV-LED photoreactor.
- Reaction rates modelled using a modified Langmuir-Hinshelwood (L-H) rate equation.
- Quantum yield modelling using an existing CPI model.
- Poor fit observed when with L-H model data compared with experimental data.
- Modelled quantum yield followed the same trend as experimental photonic efficiency.
