Decomposition of Caffeine by DC Pin-Hole Discharge in Water Solutions

angličtina

Decomposition of caffeine as a model alkaloid by a DC diaphragm discharge is studied. Production of H2O2 during the discharge and decomposition of caffeine was evaluated by UV-VIS spectrometry starting with initial concentration of 10, 25 or 50 ppm of alkaloid. Decomposition is practically complete after 1 hour for the lowest caffeine concentration, with better energy efficiency for two higher concentrations (300 mg/kWh).
