Abstract
Section titled āAbstractāThe eco-friendly ionic liquid 1-(2-ethoxy-2-oxoethyl) pyridazinium chlorideās (EOPC) newly synthesised electro-oxidation behaviors of boron-doped diamond (BDD) and SnO 2 in an alkaline media were compared using galvanostatic electrolysis.Various pyridazinium and alkaline concentrations were studied.In addition, the temperature, and density current effect of pyridazinium oxidation were investigated.The BDD showed a higher activity toward pyridazinium oxidation than the SnO 2 .This is mainly due to the higher characteristics and the relatively inert nature of the BDD.The bulk electrolysis tests have shown that the complete removal of COD can only be achieved using a boron-doped diamond and that SnO 2 only permits a partial oxidation of pyridazinium.On the basis of the chemical oxygen demand (COD) evolution released during the treatment, a total mineralization has been proposed.Finally, electrolysis has been performed in the presence of NaCl.Based on these results, it is concluded that BDD has less poisoning effects and higher activity than SnO 2 for the selective electro-oxidation of pyridazinium.
