O-(β-hydroxyethyl)rutosides determination by micellar flow injection (FI) spectrofluorimetry
(Elsevier, 2014-07)
A simple, eco friendly, sensitive and economic flow injection spectrofluorimetric method was developed for the determination of O-(β-hydroxyethyl)rutosides. The procedure was based on the use of an anionic surfactant such ...
Determination of the oxidation stability of biodiesel and oils by spectrofluorimetry and multivariate calibration
(2011)
Oxidation stability is an important quality parameter for biodiesel. In general, the methods used to evaluate the oxidation stability of oils and biodiesels are time-consuming. This work reports the use of spectrofluorimetry, ...
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 ...
Prediction of properties of biodiesel-diesel blends using spectrofluorimetry and multivariate calibration
(2012)
Regressions based on fluorescence spectroscopy were developed to provide relatively inexpensive and rapid measurements of the concentration, viscosity, and specific gravity of biodiesel-diesel blends. The methods involved ...
Sequential spectrofluorimetric determination of free and total glycerol in biodiesel in a multicommuted flow system
(SPRINGER HEIDELBERG, 2011)
A new procedure for spectrofluorimetric determination of free and total glycerol in biodiesel samples is presented. It is based on the oxidation of glycerol by periodate, forming formaldehyde, which reacts with acetylacetone, ...
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 ...
