The chemiluminescence arising from the reaction of bis(2,4,6-trichlorophenyl)oxalate with hydrogen peroxide in the presence of dithranol has been studied. The influence of concentration of peroxyoxalate, hydrogen peroxide, dithranol, catalyst and temperature on the resulting chemiluminescence was investigated. The kinetic parameters for the peroxyoxalate-chemiluminescence of dithranol were eval...

Peroxyoxalate chemiluminescence (PO-CL) spectra obtained simultaneously and continuously using a CCD spectrometer provide evidence of the complexity of PO-CL reactions.

peroxyoxalate system includes an oxalate ester, peroxide and a fluorescer, the energy resulted from the reaction of oxalate ester and peroxide is transferred to fluorescer and cause it to fluorsc. the effect of reactants chemical structure, their concentration, solvent media (polarity and viscosity) and the temperature, on the intensity of the illuminated light with respect to time have been st...

The chemiluminescence (CL) arising from the reaction of bis(2,4,6-trichlorophenyl)oxalate (TCPO) with H2O2 in the presence of a novel blue fluorescer, furandicarboxylate derivative, has been studied. The relationship between the CL intensity and concentrations of peroxyoxalate, sodium salicylate, H2O2 and furandicarboxylate derivative as fluorescer has been investigated. Kinetic parameters for ...

Chemiluminescence (CL) is a very promising method for applications in analytic chemistry and biological systems due to the elimination of external light source, which could reduce autofluorescence interference improve signal-to-noise ratio (SNR) tissue penetration depth. The fluorescent dyes, chemiluminescent initiator, reaction temperature are three crucial factors that determine chemiluminesc...

Sensitive and selective methods, based on chemiluminescence reactions, were introduced for determination of reactive oxygen species (ROS) and their applications to biological samples and health foods. First, a sensitive method for determination of H(2)O(2) by peroxyoxalate chemiluminescence (PO-CL) was developed. This method could be applied to determine small amounts of H(2)O(2) in cola drinks...

A novel, simple, cheap, and high sensitivity batch chemiluminescent method for the determination of catecholamine drugs, epinephrine (E), dopamine (DA) and methyldopa (MD) at microgram levels in pharmaceutical formulations is described. The method is based on a chemiluminescence (CL) system arising from the reaction of bis(2,4,6-trichlorophenyl) oxalate (TCPO) with H₂O₂ in the presence of a nov...
