The Cover Feature shows a glass reactor in which Orange II (ORII) is degraded by H 2 O 2 in a basic carbonate buffer solution catalyzed by Mn III (TPPS). Under these conditions the catalyst is rapidly oxidized to (TPPS)Mn V =O, which reacts with ORII and returns to Mn III (TPPS)...
The MnIII(TPPS)/H2O2 system was found to degrade ORII with high efficiency under ambient conditions in carbonate buffer solutions. In order to gain further insight into the degradation mechanism, detailed kinetic studies using rapid‐scan spectrophotometry as a function of [H2O2], [MnIII(TPPS)] ...
