Online naphazoline quality control by micellar-enhanced spectrofluorimetry
(John Wiley & Sons Ltd, 2011-11)
The aim of this study was to develop a method for online spectrofluorimetric quality control of naphazoline (NPZ) in pharmaceuticals and raw drugs. A combination of a flow-injection analysis (FIA) system with micellar-enhanced ...
Sensitive surfactant-mediated spectrofluorimetric determination of sildenafil
(Royal Society of Chemistry, 2010-05)
Two simple and sensitive surfactant-mediated spectrofluorimetric methods for the determination of sildenafil are proposed in this paper. These methods are based on the interaction of sildenafil with normal micelles of HTAB ...
Supramolecular analytical chemistry: Spectrofluorimetric determination of 6-hydroxymelatonin with hydroxypropyl-β-cyclodextrin
(Arkat, 2011-05)
The effect of the addition of native (α, β and γ) and derivative (methyl-β and hydroxypropyl-β) cyclodextrins (CD) on the fluorescence of 6-hydroxymelatonin (6HM) in water solutions was studied. The fluorescence of the ...
On-line micellar-enhanced spectrofluorimetric determination of rhodamine dye in cosmetics
(Elsevier Science, 2008-03)
A simple FI-fluorimetric analytical methodology for the continuous and sequential determination of rhodamine B (RhB) in cosmetic products has been developed and evaluated in terms of sensibility and selectivity. The influence ...
A novel fluorimetric method for glyphosate and AMPA determination with NBD-Cl and MCR-ALS
(Pergamon-Elsevier Science Ltd, 2019-05)
We report the development of a new analytical method for the quantification of N-(phosphonomethyl)glycine (glyphosate) and (aminomethyl)phosphonic acid (AMPA) by combining spectrofluorimetry and multivariate calibration. ...
Novel spectrofluorimetric method for boldine alkaloid determination in herbal drugs and phytopharmaceuticals
(Pergamon-Elsevier Science Ltd, 2017-04-21)
A new green on-line method for Boldine determination (BOL) in herbal drugs andphytopharmaceuticals, using its native fluorescence in acid media (λex = 282 nm; λem = 373 nm) has been developed. The presented methodology ...
Flow injection spectrofluorimetric determination of carvedilol mediated by micelles
(Elsevier Science, 2008-06)
A novel flow injection (FI)-spectrofluorimetric methodology for the determination of carvedilol in microheterogeneous medium has been developed. In the sodium dodecyl sulfate (SDS) surfactant medium, an additional fluorescence ...
High-performance liquid chromatography with fast-scanning fluorescence detection and multivariate curve resolution for the efficient determination of galantamine and its main metabolites in serum
(Elsevier Science, 2012-06)
Based on green analytical chemistry principles, an efficient approach was applied for the simultaneous determination of galantamine, a widely used cholinesterase inhibitor for the treatment of Alzheimer's disease, and its ...
A novel application of immobilization on membranes for the separation and spectrofluorimetric quantification of amiloride and furosemide in pharmaceutical samples
(Elsevier Science, 2010-02-21)
A new, simple and highly sensitive method for spectrofluorimetric determination of amiloride (AMI) and furosemide (FUR) in pharmaceuticals is presented. The proposed method is based on the separation of AMI from FUR by ...
Micelles mediated separation fluorimetric methodology for Rhodamine B determination in condiments, snacks and candies
(Elsevier, 2012-09)
Dye Rhodamine B (RhB) has been widely used in textile industry and foodstuffs but due to its proved carcinogenicity and toxicity on human, many countries have forbidden its use in foods. A new methodology is proposed for ...
