Ten new methods for the determination of malonaldehyde are compared with the thiobarbituric acid

The CoY-2 was generated in the electrode cavity by reduction of 1.0 X 1C-2F CoYwhich is a substitution-inert complex. The solution contained 0.50F NaBr to increase the reversibility of the CoY-2 oxidation (1). The experiment consisted of generating CoY-2 for a measured time, tf, turning off the current for time, td, and then reversing the direction of current flow and recording an anodic chronopotentiogram corresponding to the amount of CoY-2 which had not reacted with the excess Ni+2 ion. The
