Spectrophotometric determination of rosuvastatin in pharmaceutical formulations using quinalizarin
This work presents the development of a methodology based on the formation of a charge transfer complex between quinalizarin and rosuvastatin, allowing for the spectrophotometric determination of rosuvastatin at 579 nm. The factors involved in the sensitivity of the technique were studied (nature and proportion of the solvent, reaction time, pH of aqueous phase and quinalizarin concentration). ...
متن کاملSolvent 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 کاملTrace determination and separation of tin (II) by floatation-spectrophotometric using kalmagyte and CTAB
ABSTRACTA novel floatation-spectrophotometric extraction method was developed for the recovery of tin (II) from aqueous samples prior to determination by UV spectrophotometric detection. The method is based on the formation of a complex between tin (II) and kalmagyte in pH=8. The complex is floated in the interface of n-hexane and aqueous phases. After removing the aqueous phase, the floated pa...

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...
