✦ Synopsis

The kinetics of oxidation of SCN-by DPC has been investigated in alkaline medium The reaction shows first-order dependence in [SCN -). The pseudo-first-order rate constant (&obs) changes differently under different [OH-( At low /OH-1. fobs decreases when jOH-1 increases, but when 1OH-I increases to enough extent, kob5 increases with increase in [ O H -\ . Free radicals were observed in the process of reaction A plausible mechanism involving C u ( H L ) , and CuL as active substrates in the reaction has been proposed. The rate equations derived from the mechanism explain all the experimental phenomena satisfactorily. o 1996 lohri Wiley G. Sons, Inc
