[a] 1Introduction Thec hange in hair color is ap ractice widely used by men and women to improve the appearance.R ecent research shows that 8-25 %o fm en and 75 %o fw omen in Denmark and the US make use of hair dye.T hese numbers are even higher in Japan, whose hair coloring reaches 85 %o fw omen and 33 %f or men before 20 years [ 1,2]. Hair colorants are classified as permanent, semi-permanent and temporary hair dyes [3].T he class of temporary dyes is used with the aim to provide ar apid change in hair coloring, but not persistent fixation and is marketed in the form of lotions,s hampoos,s prays and others [3,4]. Ther eleaseo ft hese dyes in the wastewaters from washes in salons is ag reat environmental problem and has demandeda nalyticalm ethods for its determination [ 5,6]. Amongt hem,t he determination of basic blue 41 (BB-41 dye) has gained attention, since it is widely used in these products.I ts determination is described by PELEZ-CID et. al. using capillary electrophoresis with electrochemical detection [7].S eparations were conducted with as olvent mixture of acetonitrile/methanol (75 :25, v/v) containing 1mol L À1 acetic acid and 10 mM sodiuma cetate.T he limit of detection was 1.49 mmolL À1.H owever, these methodsu sually require large amounts of samples, sample preparation,h igh analysis time,g reat use of solvents and the detection is not compatible with the level required for surface or drinking water treatment plant for instance.Taking into account that the BB-41 dye bear azo group easily reduced [8],n ew electrochemical methods focused on their determination using rapid,p racticable and sensible sensor should be very relevant. Forthis the use of graphene as modifier is proposed.Graphene is af lat sheet of carbon atoms with sp 2 bonds that are densely compacted, and extremely thin,assembled in ah exagonalc rystalline structure [9,10].D ue to its structural, electrical, chemical, optical, and mechanical extraordinary properties and large surface area, graphene and its derivatives have attracted great interest in their applications in the constructiono fe lectrochemical sensors in aw ide range of detection possibilities [11,12]. Thus,t he surface modification of screen-printed electrodes with graphenec ould be av iable alternative measure of BB-41 dye at low concentration using disposable electrodes.W ang et al. have demonstrated that screen-printed electrodes modified for bismuth/graphene/ionic liquid Abstract:T his paper describes ar apid and sensitive methodf or determination of the hair dye Basic Blue 41 in wastewater samples using screen-printedc arbon electrodes modified with graphene (SPCE/Gr).

Carbon nanotubes have received enormous attention in the development of electrochemical sensors by promoting electron transfer reactions, decreasing the work overpotential within great surface areas. The growing concerns about environmental health emphasized the necessity of continuous monitoring of pollutants. Pesticides have been successfully used to control agricultural and public health pests; however, intense use can cause a number of damages for biodiversity and human health. In this sense, carbon nanotubes-based electrochemical sensors have been proposed for pesticide monitoring combining different electrode modification strategies and electroanalytical techniques. In this paper, we provide a review of the recent advances in the use of carbon nanotubes for the construction of electrochemical sensors dedicated to the environmental monitoring of pesticides. Future directions, perspectives, and challenges are also commented.

“…The literature reports several analytical methods for the determination of hair dyes in commercial formulations or in wastewater, using chromatographic [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30] or electroanalytical methods [31][32][33]. However, although determination of synthetic colorants extracted from hair can be useful in many ways, the analyses require low detection limits and the literature is lacking in suitable techniques for this purpose.…”

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 electrode to pre-concentrate carboxyl-functionalyzed magnetic nanoparticles (CFMP) employed to collect the dye in solution, hence increasing the sensitivity of the analysis. The Basic Brown 16 dye, which is widely used in temporary hair dying, was chosen as a model compound. After 15 s of reaction between 1.5 × 10 −5 mol L −1 of dye and 0.1 mg mL −1 of carboxyl-functionalyzed magnetic nanoparticles in phosphate buffer electrolyte at pH 7.0, the derivative dye was collected during 40 s at the graphite-epoxy composite electrode and then transferred to a new solution of phosphate buffer at pH 7.0. The dye presented a peak current at a potential of 0.42 V that was almost 400 times higher than without the preconcentration step, suggesting that the dye was pre-accumulated due to strong magnetic interaction with the composite electrode. Under optimized conditions, the analytical curve constructed using square wave voltammetry was linear for BB16 dye concentrations between 1.00 × 10 −7 and 1.00 × 10 −6 mol L −1. The limits of detection and quantification were 1.01 × 10 −8 and 2.37 × 10 −8 mol L −1 , respectively. The proposed method was successfully applied in the determination of BB16 dye extracted from a dyed hair strand sample by alkaline digestion.
