Comparison of chemiluminescence methods for analysis of hydrogen peroxide and hydroxyl radicals

Abstract

Assessment of alpha radiolysis influence on the chemistry of geologically disposed spent fuel demands analytical methods for radiolytic product determination at trace levels. Several chemiluminescence methods for the detection of radiolytic oxidants hydrogen peroxide and hydroxyl radicals are tested. Two of hydrogen peroxide methods use luminol, catalyzed by either µ-peroxidase or hemin, one uses 10-methyl-9-(p-formylphenyl)-acridinium carboxylate trifluoromethanesulfonate and one potassium periodate. All recipes are tested as batch systems in basic conditions. For hydroxyl radical detection luminophores selected are 3-hydroxyphthalic hydrazide and rutin. Both methods are tested as batch systems.The results are compared and the applicability of the methods for near-field dissolution studies is discussed.

A novel microarray chemiluminescence method based on chromium oxide nanoparticles catalysis for indirect determination of the explosive triacetone triperoxide at the scene

“…However, the traditional CL catalysts are limited due to their poor catalytical effect in the lower concentrations of luminol and H 2 O 2 . [20][21][22] Nanotechnology opens the door to innovations. Chromiumbased catalysts have been widely applied in polymerization, hydrogenation and dehydrogenation of hydrocarbons, dehydrogenation of alcohols to produce aldehydes, ketones and alkenes, dehydrocyclization of paraffins, water gas shi reaction and decomposition, and so on.…”

Reactions induced by electrical discharges in pollutant abatement and bacterial inactivation

“…Spin trapping with DMPO (5.5 dimethyl-pyrroline-N-oxide) [13], ESR methods are also reported [14,16] complementary with fluorescence methods 19]. Pehrman et al [20]compared various analysis methods.…”

Periodate oxidation and its contribution to instrumental methods of micro-analysis—A review

“…The hydrogen peroxide-potassium periodate-potassium carbonate chemiluminescence system was employed in a FIA system for the determination of (a) trace amounts of H 2 O 2 in snow water [145], (b) of H 2 O 2 produced from the radiolysis of geologically disposed spent fuel [146] and (c) of sodium dodecyl benzene sulphonate salt based on its enhanced CL-emission effect [147].…”
