Spectrophotometric determination of phenylephrine hydrochloride in pharmaceuticals by flow injection analysis exploiting the reaction with potassium ferricyanide and 4-aminoantipyrine.
This paper presents a method for the determination of phenylephrine hydrochloride in pharmaceuticals by spectrophotometric flow injection analysis exploiting the reaction with potassium ferricyanide and 4-aminoantipyrine, which leads to the formation of a condensation product with strong absorptivity at 500 nm. The linear dynamic range was between 0.95 and 9 mg/L, with a limit of detection of 0...
متن کاملDetermination of polyphenols in wines by reaction with 4-aminoantipyrine and photometric flow-injection analysis.
A new flow-injection analytical procedure is proposed for the determination of the total amount of polyphenols in wines; the method is based on the formation of a colored complex between 4-aminoantipyrine and phenols, in the presence of an oxidizing reagent. The oxidizing agents hexacyanoferrate(III), peroxodisulfate, and tetroxoiodate(VII) were tested. Batch trials were first performed to sele...
متن کاملSpectrophotometric Assay of Phenylephrine Hydrochloride Using 4-Aminoantipyrine and Copper (II)
A new spectrophotometric method is proposed for the determination of phenylephrine hydrochloride. The method is based on the coupling of 4-aminoantipyrine (4-AAP) with Phenylephrine Hydrochloride (PEH) to give a new ligand that reacts with copper (II) in the presence of sodium tetraborate buffer solution of pH9 at 50°C with an intensely red colored chelate having maximum absorption at 480 nm. T...
متن کاملDetermination of phenylephrine hydrochloride by flow injection analysis with chemiluminescence detection.
A new method is proposed for the determination of phenylephrine hydrochloride by flow injection analysis with direct chemiluminescence detection. The method is based on the oxidation of the drug by potassium permanganate in sulfuric acid medium at 80 degrees C. The calibration graph is linear over the range 0.03-8 ppm phenylephrine hydrochloride, with a relative standard deviation (n = 51, 0.5 ...
متن کاملFlow Injection Spectrophotometric determination of Doxorubicin Hydrochloride in Urine samples
A simple and fast FI colorimetric procedure for determination of doxorubicin hydrochloride (DXH) was proposed. It is based on the redox reaction between iron (III) and DXH, resulting in an intensely red colored complex in the presence of 1, 10-orthophenantroline which can be followed by spectrophotometric measurement at λmax= 510 nm. This is an automatic way to determine doxorubicin hydrochlori...
