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 ...

Complexation (cucurbit[6]uril-pyrene): Thermodynamicand spectroscopic properties
(Elsevier Science, 2014-10)
The influence of the macrocyclic compound cucurbit[6]uril (CB6) on the photophysical properties of the fluorophore pyrene (PYR) has been studied. Guest–host interaction was observed by UV–visible spectroscopy and ...
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. ...
Determination of sildenafil by preconcentration on surfactant coated polymeric resin followed by spectrofluorimetry

The illicit addition of phosphodiesterase type-5 (PDE-5) inhibitors like sildenafil (Viagra) in product offered as herbal medicine or dietary supplement for male erectile dysfunction has concerned authorities in recent ...
Sensitive ergotamine determination in pharmaceuticals and biological samples using cloud point preconcentration and spectrofluorimetric detection
(Elsevier, 2013-01)
A new cloud point extraction (CPE) method for ergotamine analysis using fluorimetric detection is described. Ergotamine from an aqueous solution was preconcentrated into a smaller surfactant-rich phase using nonionic ...
