The stoichiometry of O2 evolution in the Fe3+ catalyzed decomposition of H202 in dilute HCIOa a t high [FeS+]/[H202] ratios is 2H202 -+ 2H20 + O2 with no deficiency indicating accumulation of an intermediate complex. This and the observed kinetics are shown to be consistent with a "redox chain" but

Abstract
Predictions of the βredoxβ and βcomplexβ schemes for the Fe^3+^ catalyzed decomposition of H~2~O~2~ have been compared with published and new experimental data by numerical integratior of the appropriate complete sets of differential equations. Apparent discrepancies for the redox scheme at high Fe^3+^/H~2~O~2~ ratios are shown to disappear in the complete treatment, and inconsistencies of the complex scheme with both kinetic data and spectroscopic measurements are pointed out.

The use of hydrogen peroxide in addition to ferrous and ferric salts has been shown an effective method in the decoloration of indigocarmine (IDS), Indigo-5,5Π-disulfonic acid disodium salt. The kinetic experiments control have been carried out by means of a conventional spectrophotometric techniqu
The decomposition of hydrogen peroxide by ferric ion adsorbed on cellulose, the lowering of the degree of polymerization of cellulose, and the graft copolymerization in the systems containing methyl methacrylate were studied. As the amount of ferric ion adsorbed on cellulose and the concentration of
