Spectrophotometric Determination of Catecholamines based on their Oxidation Reaction Followed by Coupling with 4-Aminobenzoic Acid
Um método espectrofotométrico simples e sensível para a determinação de dopamina, metildopa, levodopa e catecol, puros, em formulações farmacêuticas, e em água, é descrito. O método é baseado na reação de oxidação com periodato, seguida pelo acoplamento oxidativo com ácido 4-aminobenzóico em pH 4, levando à formação de produtos coloridos. O gráfico de calibração foi linear no intervalo de 0,20-...
متن کاملSpectrophotometric determination of catecholamines with metaperiodate by flow-injection analysis
A flow-injection spectrophotometric method for the determination of adrenaline and isoprenaline, based on the reaction with metaperiodate, is described. The calibration graphs are linear up to 2X 10e4 M. Flow injection allows the measurement of 120 samples per hour. The method was successfully applied to the determination of both catecholamines in pharmaceuticals.
متن کاملSPECTROPHOTOMETRIC REACTION RATE METHOD FOR THE DETERMINATION OF SLWR BASED ON ITS CATALYTIC EFFEICT ON THE OXIDATION OF GLLOCYANW BY PER0XYDISULPTE
A sensitive and selective procedure was developed for the spectrophotometric determination of silver by its catalytic effect on the oxidation of gallocyanine by peroxydisulphate in acidic media at 540 nm. Silver can be determined in the range of 0.001-0.500 µg/ml with a limit of detection of 0.0005 µg/ml, by a fixed-time method of 4.0 min from initiation of the reaction, The relative standa...
متن کاملKinetic-Spectrophotometric Determination of Thiocyanate Based on Its Inhibitory Effect on the Oxidation of Pyrogallol Red by Bromate
A kinetic spectrophotometric method for rapid measurement of thiocyanate in serum, urine and sewage water with no need for removed of interfering substances in described. The method is based on the inhibitory effect of thiocyanate on the oxidation of pyrogallol red by bromated and nitrite which is monitored at 467 nm. The variables affecting the rate of the reaction were investigated and th...
متن کاملSpectrophotometric determination of periodate, iodate and bromate mixtures based on their reaction with iodide.
A rapid, simple, precise and accurate method is proposed for the determination of ternary mixtures of periodate-iodate-bromate based on their reaction with iodide ion at different pH values. The absorbance was measured at 352 nm. Three sets of reaction conditions were developed. In the first set of conditions, only periodate reacted with iodide, but in the second set the periodate and iodate re...
