Degradation of Crystal Violet by Pulsed Corona and Spark Discharge: Determination of Removal Mechanism

Article Preview

Abstract:

The pulsed discharge includes corona discharge and spark discharge. The voltage waveforms, photo, the decoloration rate of Crystal violet in corona discharge and spark discharge were investigated respectively. The results show that the spark discharge is more intense than the corona discharge. The decoloration rate of Crystal violet by spark discharge is 90%, which is higher than that corona discharge. From the UV-Visible and FTIR spectra, we can see that the molecular conjugated system and the benzene ring of CV were damaged by pulsed discharge.
