From: Remediation of chromium-slag leakage with electricity cogeneration via a urea-Cr(VI) cell
Variation of cell voltage and Cr(VI) concentration in the leakage with time under different systems.
(1.0 M PBS (red), 1.0 M KOH (black)), containing 1.0 M urea and fixing catholyte Cr(VI) at 3.0 mM in 0.5 M H2SO4, with a constant load of 985 Ω.).
