Fig. 4From: Electricity-assisted production of caproic acid from grassCaproate concentration and cyclic voltammetry of Kolbe electrolysis process: a Caproate concentration over the period of Kolbe electrolysis, and b cyclic voltammetry of solution before Kolbe electrolysis. Control (red line) contained only 0.5 M Na2SO4 in water, synthetic solution (green line) contains 0.1 M caproic acid and 0.5 M Na2SO4 in water, and real solution (blue line) was the anolyte from electrochemical extraction systemBack to article page
