Derivative Spectrophotometric Determination of Trace Amounts of Tungsten (vi) in Real Water Samples
2,4-Dimethoxybenzaldehydeisonicotinoylhydrazone (DMBHIH) has been synthesized and characterized with IR, NMR and Mass Spectroscopic methods. A simple and derivative spectrophotometric method has been developed for the determination of trace amounts of W (VI). The reagent forms an yellow coloured water soluble complex with W (VI) in bacic medium (pH 8.0). The molar absorptivity and Sandell’s sen...
متن کاملExtractive spectrophotometric determination of tungsten(VI) in alloy steels using ethopropazine hydrochloride.
Ethopropazine hydrochloride (EPH) has been proposed as a sensitive reagent for the spectrophotometric determination of tungsten(VI). The method is based on the formation of a chloroform-soluble yellow-colored ternary complex by the interaction of EPH and thiocyanate with tungsten(V). The complex exhibits the absorption maximum at 404 nm with Sandell's sensitivity value of 20.03 ng cm-2. The com...
متن کاملSpectrophotometric and derivative spectrophotometric determination of aluminium with Hydroxynaphthol Blue.
The reaction of aluminium(III) with Hydroxynaphtol Blue (HNB) in aqueous media at apparent pH 5.5 results in a red complex that is stable for at least 4 hr. Beer's Law is obeyed up to 1.6 microg/ml of aluminium(III) with an apparent molar absorptivity of 1.66 x 10(4) l.mol(-1). cm(-1) at 569 nm. This paper proposes procedures for aluminium(III) determination by ordinary and first-derivative spe...
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 کاملKINETIC DETERMINATION OF ASCORBIC ACID a WITH SPECTROPHOTOMETRIC DETECTION
A simple and rapid method has been developed for the determination of ascorbic acid in fruit and pharmaceutical products. The method is based on the measurement of the reaction rate between ammonium molybdate and ascorbic acid in acidic media. The reaction was monitored spectrophotometrically at 800 nm by fixed-time and variable-time methods. The calibration graph was linear in the range of...
