Solvent Extraction and Spectrophotometric Determination of Magnesium by Paratoly l-2-Thenohydroxamic Acid and Quinalizarin
Magnesium is extracted with a chloroform solution of N-p-tolyl-2- thenohydroxamic acid (PTTHA) from aqueous solution of pH 9.5 .Mg-PTTHA complex is colourless and the colour is developed by adding quinalizarin into the extract. lmax and e of the complex are 590nm and 2.8´103 Lmol -1cm-1respectively.Most common ions do not interfere in the determination of magnesi...
متن کاملDetermination of chlorpheniramine maleate and tincture ipecac in dosage form by liquid chromatography with ultraviolet detection.
A procedure was developed and validated for measuring chlorpheniramine maleate and tincture ipecac (as emetine hydrochloride) by reversed-phase liquid chromatography with methanol-10 mM sodium heptanesulfonate (20 + 30) as the mobile phase; the pH was adjusted to 4 with acetic acid, and the flow rate was at 1.5 mL/min, with ultraviolet detection at 254 nm. Propyl paraben was used as the interna...
متن کاملVisible Spectrophotometric Determination of Chlorpheniramine Maleate and Diphenhydramine Hydrochloride in Raw and Dosage form Using Potassium Permanganate
Two simple, rapid and sensitive spectrophotometric methods developed for Chlorpheniramine Maleate (CPM) and Diphenhydramine Hydrochloride (DPH) determination in pure and pharmaceutical preparation using Potassium Permanganate. The solvent system used was potassium permanganate. The method developed by adding a known amount of permanganate to CPM and DPH in acid and alkaline medium, the unreacte...
متن کاملExtraction - Spectrophotometric Determination of Palladium with Tetrabutyl Ammonium Iodide
A sensitive and selective extraction - spectrophotometric method for the determination of trace amounts of palladium is reported. The method is based on quantitative extraction of brownish tetrabutylammoium tetraiodopalladium (II) ion pair into a small valume of chloroform at pH 1.3-12.0, followed by spectrophotometric measurements. The Beer's law is obeyed over the range 0.02-1.09 <em...
متن کاملSimultaneous Determination of Chlorpheniramine Maleate, Phenylephrine Hydrochloride, Paracetamol and Caffeine in Pharmaceutical Preparation by Rp-hplc
A reversed-phase High-Performance Liquid-Chromatography (RP-HPLC) method was successfully developed for the simultaneous determination of quaternary mixture consisting of chlorpheniramine maleate (CPM), phenylephrine hydrochloride (PE), paracetamol (PCM) and caffeine in pharmaceutical preparation. The method was found to be simple, sensitive and rapid. The separation of the drugs was carried ou...
