Micro Reactor For Chlorophenols Electrocathalytic Oxidation

Abstract

Chlorophenols are universal priority pollutants listed by all Environmental Agencies. The removal of chlorophenols from contaminated waters is carried out by microbiological and chemical methods. In this work is presented a combination of three methods that are electrochemical oxidation, electrochemical reduction and photo-Fenton-oxidation. Results performed in a micropilot reactor showed that it is feasible to degrade chlorophenols by these combined methods, with a removal rate of 82%, at a current density of 6.66 Adm -2 . The current efficiency was calculated and the results indicated that this combined method is more efficient that separated ones (electrochemical oxidation or reduction).

Liquid phase oxidation chemistry in continuous-flow microreactors

“…Similar setups, both commercially available and custom made ones, have been used by others to enable oxidations of furan, 312 chlorophenols, 313 and cyclic amines (Shono oxidation). [314][315][316] 6.5 TEMPO, HOX, hypervalent iodine and oxone mediated oxidation processes in continuous flow Oxidation reactions which do not require transition metal catalysts are appealing since there is no need for removal and regeneration of precious metals.…”
