文摘
- •
Degradation of Malachite Green oxalate solutions at pH 3.0 by AO, AO-H2O2, EF and PEF.
- •
A Pt anode leads to slower decolorization and mineralization than BDD.
- •
Up to 97% mineralization by the most powerful PEF process with BDD at 100 mA cm−2.
- •
Study of the evolution of seven final short-chain aliphatic carboxylic acids.
- •
Conversion of the initial N atoms of the dye mainly into NH4+, along with small amounts of NO3−.
