Flow-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 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 کاملKinetic spectrophotometric method for the determination of silymarin in pharmaceutical formulations using potassium permanganate as oxidant.
A new simple and sensitive kinetic spectrophotometric method for the determination of silymarin in pure form and in pharmaceutical formulations is described. The method is based on the oxidation of the drug with potassium permanganate at pH 7.0 +/- 0.2. The reaction is followed spectrophotometrically by measuring the decrease in the absorbance at 530 nm. The calibration graph is linear in the r...
متن کاملDetermination 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) ...
