摘要

Kinetics of oxidation of indigo carmine (IC) by sodium N-haloarenesulfonamidates (RNXNa, where R= CH 3 C 6 H 4 SO 2− or C 6 H 5 SO 2− and X= Cl or Br) chloramine T (CAT), bromamine T (BAT), chloramine B (CAB), and bromamine B (BAB) in alkaline buffer (pH 9– 11) has been followed spectrophotometrically at λ max= 610 nm. Rate law,–d [IC]/dt= k [OX] 0 [IC] 0 [OH−] x where x< 1, is obeyed. The reaction products, benzenesulfonamide and ...
