✦ Synopsis

sufficient excess of cobalt, the Brdicka polarographic catalytic hydrogen currents of Jow molecular weight thiols frequently exhibit typical kinetic characteristics. A detailed investigation of these currents has revealed also a marked adsorption component. A mechanism which leads to the formation of the BrdiEka currents was suggested on the basis of the changes of these currents with a number of factors. Under thespecifiedconditions theBrdiekacataJyticwavemay bedistorted; theobserveddeformationsareeitherdue to the modification of the proper Brdieka current, or they are a consequence of the simultaneous appearance of another type of the catalytic hydrogen current, which can also exist in the transition metaJ/Jigand systems. * ir, catalytic hydrogen currents of the thiol itself in the absence of the cobalt ions.
