The Decomposition of Hydrogen Peroxide by Liver Catalase
1. The velocity of decomposition of hydrogen peroxide by catalase as a function of (a) concentration of catalase, (b) concentration of hydrogen peroxide, (c) hydrogen ion concentration, (d) temperature has been studied in an attempt to correlate these variables as far as possible. It is concluded that the reaction involves primarily adsorption of hydrogen peroxide at the catalase surface. 2. Th...
متن کاملDecomposition of solid amorphous hydrogen peroxide by ion irradiation.
We present laboratory studies of the radiolysis of pure (97%) solid H2O2 films by 50 keV H+ at 17 K. Using UV-visible and infrared reflectance spectroscopies, a quartz-crystal microbalance, and a mass spectrometer, we measured the absolute concentrations of the H2O, O2, H2O2, and O3 products as a function of irradiation fluence. Ozone was identified by both UV and infrared spectroscopies and O2...
متن کاملIsothermal decomposition of hydrogen peroxide dihydrate.
We present a new method of growing pure solid hydrogen peroxide in an ultra high vacuum environment and apply it to determine thermal stability of the dihydrate compound that forms when water and hydrogen peroxide are mixed at low temperatures. Using infrared spectroscopy and thermogravimetric analysis, we quantified the isothermal decomposition of the metastable dihydrate at 151.6 K. This deco...
متن کاملThe effect of the peroxide concentration and other factors on the decomposition of hydrogen peroxide by catalase.
graphic analysis detected traces of Cr+++ in all organs, with most in thyroid and spleen. The relationship.between the activation by Mn++ and that by Mg++ +Cr++++HDP is curious. The variability in the ratio of these two activities (see Table 6) at first indicated that two different enzymes might be concemed, but the absence of any marked change in the ratio during the purification of the enzyme...
متن کاملCatalytic Decomposition of Hydrogen Peroxide in the Presence of Synthesized Iron-Manganese oxide Nanocomposites via Different Methods
The special application of iron-manganese oxide nanocatalysts has been investigated in decomposition of hydrogen peroxide. In this research, iron-manganese oxide nanocomposites were synthesized by co-precipitation, sol-gel and mechanochemical methods using iron (III) nitrate, iron (II) sulfate and manganese (II) nitrate as starting materials. These nanocomposites were prepared on the variou...
