Hydrogen and oxygen isotope values in hydrogen peroxide

Rapid Communications in Mass Spectrometry, 2011
Hydrogen peroxide (H 2 O 2 ) is a widely used oxidizer with many commercial applications; unfortunately, it also has terrorist‐related uses. We analyzed 97 hydrogen peroxide solutions representing four grades purchased across the United States and in ...

Peroxide value determination—Comparison of some methods

Journal of the American Oil Chemists' Society, 1974
AbstractA comparison between the determination of the peroxide value by the methods of Wheeler and Sully (iodometric titration) and that of Stine, et al. (ferric thiocyanate method) was made. Some oxidized vegetable oils, H2O2, t‐butyl hydroperoxide, cumene hydroperoxide, methyl oleate hydroperoxides, and methyl linoleate hydroperoxides were used as ...

Comparison of Peroxide Value Methods Used for Semihard Cheeses

Journal of Agricultural and Food Chemistry, 2002
The objective was to evaluate alternatives to the peroxide value method of choice in the dairy industry, the method issued by the International Dairy Federation. Furthermore, the study evaluated the feasibility of alternative solvents for extracting lipids and subsequent peroxide value determinations.

Increased levels of lipid peroxides in aged rat brain as revealed by direct assay of peroxide values

Neuroscience Letters, 1990
Lipid peroxide concentrations in brain tissues of young and aged rats were determined by a direct method for measuring peroxide values. Three different brain regions were analyzed for lipid peroxides. The peroxide levels increased in all three regions of aged as compared to those of young rats, while lipid peroxides in plasma appeared to be stable ...

Semiautomated Thiocyanate Method for Determining Peroxide Values of Lipids

Journal of Food Science, 1969
SUMMARY– A liquid‐flow semiautomated ferrous thiocyanate procedure, designed for use in monitoring peroxide values of extracted oils, is presented. Twenty samples per hour can be measured by means of a system using conventional manifold tubing and AutoAnalyzer components.
