Chemiluminescence Determination of Atropine using Luminol-Hemin-H2O2 System

A sensitive and fast chemiluminescence (CL) method has been described for the direct determination of atropine. The method is based on the quenching effect of atropine on the CL signals of the luminol– H2O2 reaction catalyzed by hemin in an alkaline medium. Hemin could strongly enhance the chemiluminescence of the luminol–H2O2 system. The luminophor of the luminol–H2O2–hemin CL system was ident...

Chemiluminescence Determination of Hydroxyzine and its Metabolite Cetirizine

A chemiluminescence (CL) method has been developed for the determination of Hydroxyzine (Hyd) and its metabolite Cetirizine (Cet). The method is based on sensitizing effect of Cet and Hyd on the weak CL reaction between Ru(phen)32+ and acidic Ce(IV). A mechanism for the CL reaction has been proposed on the basis of UV-Vis, fluorescent and CL spectra. By using the recommended procedure, the cali...

Chemiluminescence determination of melamine with Luminol-K3Fe(CN)6 system

A sensitive chemiluminescence (CL) method was developed for determining melamine in urine and plasma samples based on the fact that melamine can remarkably enhance the chemiluminescence of Luminol-K3 Fe(CN)6 system in alkaline medium. The determination conditions were optimized. Under optimum conditions, the chemiluminescence intensity had a good linear relationship with melamine in the range o...

Fast determination of thiacloprid by photoinduced chemiluminescence.

A new and sensitive application of chemiluminescence detection has been developed for the determination of the pesticide thiacloprid in water. It was based on the on-line photoreaction of thiacloprid in a basic medium, with quinine acting as the sensitizer of the chemiluminescent response; cerium (IV) in sulfuric acid medium was used as the oxidant. High degrees of automation and reproducibilit...
