In this study, an adaptive pH controller is proposed to control the pH process efficiently.
To reduce the generation of large quantities of metal oxides in cathode, a pH controller is used to control the pH of the electrolyte waste solution between 0.5 and 1 for the formation of UO2+.
Experimental pH was controlled via a mixed CO2 supply where a pH controller (Parker, Castle Hill, Australia) regulated the amount of CO2 gas supplied into the airline.
Ascorbic acid and aqueous NaOH were also used as an antioxidant and pH controller, respectively.
