Use of a composite electrode modified with magnetic particles for electroanalysis of azo dye removed from dyed hair strands
(2016-12-01)
The analysis of dyes in hair samples can provide useful information for forensic purposes. The present work describes a novel method for the extraction of dye from a hair sample and its determination using a composite ...
Synthesis and evaluation of a molecularly imprinted polymer for selective adsorption and quantification of Acid Green 16 textile dye in water samples
(2017-08-01)
An alternative for determining environmental pollutants, like textile dyes, is the use of molecularly imprinted polymers (MIPs) as solid phase extraction (SPE) or as sensor recognition systems. MIPs are tailor-made artificial ...
Multivariate curve resolution applied to kinetic-spectroscopic data matrices: Dye determination in foods by means of enzymatic oxidation
(Elsevier Science, 2017-07)
In this work, the combination of chemometric techniques with kinetic-spectroscopic data allowed quantifying two dyes (tartrazine and carminic acid) in complex matrices as mustard, ketchup, asparagus soup powder, pumpkin ...

Determination of temporary dye Basic Red 51 in commercial hair dye, river water and wastewater from hairdressing salon using graphite-epoxy composite electrode modified with magnetic nanoparticles
(2020-12-01)
The present work reports the development of a simple, fast and inexpensive method for the determination of Basic Red 51 (BR 51) dye, known to be widely employed in comercial formulations of temporary dyes. The method ...
Development of an HPLC-UV/Vis method for the determination of dyes in a gasoline sample employing different pre-treatments
(Elsevier B.V., 2010-09-01)
A simple method was developed for the determination of the dyes Solvent Blue 14 (SB-14), Solvent Orange 7 (SO-7) and Solvent Red 24 (SR-24), based on high-performance liquid chromatography (HPLC) coupled with UV-Vis ...
A protein dye-binding assay on cellulose membranes for tear protein quantification: Use of conventional Schirmer strips
(2007)
PURPOSE: To develop a method to quantify tear protein concentration with the sensitivity to measure this variable in the restricted volumes of single human tear samples. METHODS: Aliquots of tear fluid from healthy subjects ...
A molecularly imprinted polymer-based evanescent wave fiber optic sensor for the detection of basic red 9 dye
(2015-10-31)
A cheap and robust method for the detection and quantification of textile dyes is the use of biomimetic sensors with optical transduction, employing a molecularly imprinted polymer (MIP) as the recognition element. This ...
