WebApr 13, 2024 · Increasing pH increases the hydrogen peroxide efficiency in generating hydroxyl radicals; however, it also accelerates the decomposition rate of hydrogen peroxide [31,32]. The created alkaline environment, with a pH between 9 and 10, optimized the activity of H 2 O 2. At pH 10, H 2 O 2 decomposed rapidly in the presence of a catalyst. WebPeroxygen bleaches. Hydrogen peroxide (HP), H 2 O 2, is a common bleaching agent as well as the starting material for almost all other oxygen-based bleach systems. Its consumption in the United States is currently in the range of 2.2 million tons (2.0 million metric tons). H 2 O 2 is a very weak acid; it is only slightly dissociated (p Ka = 11. ...
