Direct Chemiluminescence Determination of Oxymorphone Using Potassium Permanganate and Polyphosphoric Acid
Abstract A simple and sensitive chemiluminescence (CL) method was developed for direct quantification of oxymorphone, a µ opioid agonist that is approximately 10 times more potent than morphine. In this method potassium permanganate in polyphosphoric acid was used as CL reagent. Using this method, oxymorphone can be determined over the concentration ranges 13.5-337.8 ng mL-1 and 0.34-6.76...
متن کاملDetermination of protoberberine alkaloids in medicinal plants based on acidic potassium permanganate chemiluminescence system.
A simple method was established to determine protoberberine alkaloids in Cortex Phellodendri and Rhizoma Coptidis based on an acidic potassium permanganate chemiluminescence (CL) system. The optimum conditions for the CL reaction between protoberberine alkaloids and potassium permanganate were studied in detail. Under the optimum conditions, the linear response ranges for berberine, palmatine a...

متن کاملHighly Sensitive Determination of Ethylenediaminetetraacetic Acid Using a Permanganate Chemiluminescence System Catalyzed by Gold Nanoparticles.
A sensitive and selective chemiluminescence method was developed to determine ethylenediaminetetraacetic acid (EDTA) in water samples. It was observed that gold nanoparticles (AuNPs) catalyzed chemiluminescence (CL) reactions of permanganate-aldehydes which underwent an enhancement effect in the presence of iron(III) ions (Fe(3+)). This effect is more remarkable in the presence of EDTA, and a h...
متن کاملChemiluminescence 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...
