“…The main studies have included applications of chromatographic methods for detecting oxidative dye intermediates in permanent hair colorants [8][9][10][11][12][13][14][15][16][17][18][19][20][21]. Despite the importance of temporary hair dyes as water contaminants, few analytical methods are available for their determination [22][23][24][25][26][27].…”

Abstract:The present work describes the development of a voltammetric sensor for the selective determination of Acid Green 25 (AG25) hair dye, widely used in commercial temporary hair dyes. The method is based on a glassy carbon electrode modified with multiwalled carbon nanotubes activated in the presence of sulfuric acid, where the anthraquinone group present as a chromophore in the dye molecule is reduced at −0.44 V vs. Ag/AgCl in a reversible process involving two electrons in Britton-Robinson (B-R) buffer solution at pH 4.0. Analytical curves were obtained using square wave voltammetry in the range from 1.0 × 10 −7 to 7.0 × 10 −6 mol· L −1 , achieving a detection limit of 2.7 × 10 −9 mol· L −1 .The voltammograms recorded for the Acid Black 1 (AB1) dye showed that the azo groups of the dye were reduced on the carbon nanotube-modified electrode (CNTME), presenting a pair of redox peaks at −0.27 V and −0.24 V in the reverse scan. Under these experimental conditions, both dyes could be detected in the water sample, since the AG25 dye is reduced at −0.47 V. The presence of other hair dyes bearing other chromophore groups, such as Acid Black 1, Acid Red 33 and basic blue 99, did not interfere with the method, which showed an average recovery of 96.7 ± 3.5% (n = 5) for AG25 dye determination in the presence of all of these dyes. The method was successfully applied to tap water and wastewater samples collected from a water treatment plant. OPEN ACCESSChemosensors 2015, 3 23

“…Due to the health and ecological risks caused by long‐ and short‐term exposure to phenolic compounds, development of a highly sensitive and simple method for their low‐level detection is of significance for the study of toxicological analysis, foods inspection and environmental concerns. Various methods are available for the determination of benzenediols, including chromatography , spectrophotometric analyses , electrochemistry and chemiluminescent detection . Chemiluminescence (CL) analysis promises high sensitivity with simple instruments and rapidity in signal detection; when coupled with flow‐injection analysis (FIA), the FIA–CL method provides a cheap, rapid, simple and reproducible means of detection, and therefore has been extensively used in many fields.…”

Enhancing and inhibiting effects of benzenediols on chemiluminescence of a novel cyclometallated iridium(III) complex

A novel chemiluminescence (CL) system, including the cyclometallated iridium(III) complex {tris[1-(2,6-dimethylphenoxy)-4-(4-chlorophenyl)phthalazine]iridium}, potassium permanganate and oxalic acid, is proposed for the determination of benzenediols. This method is based on the fact that hydroquinone and catechol exhibited an inhibiting effect, while resorcinol exhibited an enhancing effect on CL intensity. The optimum conditions for CL emission were investigated. Under optimal conditions, the detection limits of hydroquinone, catechol and resorcinol were 6.4 × 10(-8), 2.7 × 10(-9) and 8.1 × 10(-7) mol/L, respectively. The method has been successfully applied to the determination of benzenediols in different types of water sample. The luminophors of the CL systems were all identified as the metal-ligand charge-transfer (MLCT) excited state of the iridium complex.

“…MEKC 3 has been a well‐proven selection for the determination of aromatic amines in permanent hair dyes 9, which is able to separate both charged and uncharged molecules in an electro‐osmotically driven system. For example, using tetratrimethylammonium bromide or CTAB as cationic surfactants in 50.0 mM phosphate buffer at pH 5.0, 13 dye intermediates were separated successfully by Lin et al .…”

A new type of block copolymer, which was synthesized by styrene and maleic anhydride, P(MAn-alt-St) 119 -b-PSt 558 , was successfully developed as the capillary coatings in open tubular CEC. It is interesting that the covalently bonded coatings are porous and the coatings can play the role of surfactants in the separation of aromatic amines when the buffer solution was composed of 30.0 mM ammonium acetate at pH 7.7 with 20% THF. Thus, successful baseline separation of five kinds of aromatic amines has been achieved. As validated by both artificially prepared solutions of aromatic amines and four real samples of commercially available permanent hair dyes, this proposed method was successfully applicable to the quantitative analysis of p-phenylenediamine (PPD) and ophenylenediamine (OPD) ingredients in these commercial products, with a linear range between 8.3 mM and 6.0 mM, correlation coefficient above 0.990 and recovery between 83.5 and 110.9%. The detection limit obtained from calculations based on signal-to-noise ratio (S/N 5 3) was 4.2 mM for PPD and 6.0 mM for OPD, respectively. Furthermore, the role of the surfactants played by the block copolymer coatings has been primarily explored.
