摘要：
In this paper, removal of malachite green (MG) by two separate processes, namely electrochemical oxidization polymerization and electrochemical reduction precipitation process, was studied. Reaction rate constants (k0), exchange current density i0, the transfer coefficients β and the diffusion coefficient D values were all tested. TR-FTIR (time-resolved Fourier transform infrared spectroscopy), UPLC-MS (ultra-performance liquid chromatography–mass spectrometry), and GC–MS (gas chromatography–mass spectrometer) analyses were applied to investigate the pathway and mechanism of MG degradation. The results show that both electrochemical oxidization polymerization and electrochemical reduction precipitation process were efficient to remove MG.
