Determination of ceftriaxone sodium in pharmaceutical formulations by flow injection analysis with acid potassium permanganate chemiluminescence detection.
Based on the chemiluminescence (CL) emission generated from the oxidation of ceftriaxone sodium alkali hydrolysate by potassium permanganate in polyphosphoric acid (PPA), a novel determination method for ceftriaxone sodium was developed by using a flow-injection technique. The calibration curve appears to be linear in the range between 0.05 and 100 microg mL(-1) with a detection limit (3sigma) ...
متن کاملFlow-injection determination of vanadium in seawater samples with acidic potassium permanganate chemiluminescence.
Chemiluminescence from the vanadium and potassium permanganate reaction was studied under acidic conditions to develop a sensitive method for vanadium determination using the formaldehyde enhancement effect. The method was successfully applied to the determination of vanadium in seawater. Experimental parameters were optimized, including acid concentration, potassium permanganate and formaldehy...
متن کاملDirect 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 کاملPermanganate-based chemiluminescence analysis of ferulic acid using flow injection.
A simple, sensitive and rapid flow-injection chemiluminescence method has been developed for the determination of ferulic acid based on the chemiluminescence reaction of ferulic acid with potassium permanganate in a nitric acid medium. A strong chemiluminescence signal was observed when ferulic acid was injected into an acidic potassium permanganate solution in a flow-cell. The present method a...
متن کاملFlow injection chemiluminescence determination of loxoprofen and naproxen with the acidic permanganate-sulfite system
A novel flow injection chemiluminescence (CL) method for the determination of loxoprofen and naproxen was proposed based on the CL system of KMnO4, and Na2SO3 in acid media. The CL intensity of KMnO4-Na2SO3 was greatly enhaneed in the presence of loxoprofen and naproxen. The mechanism of the CL reaction was studied by the kinetic proecss and UV-vis absorption and the conditions were optimized. ...
