“…In addition, Disperse Red 1, in a dose higher than 10 μg l −1 , causes an increase in the frequency of micronuclei in human lymphocytes and HEPG2 cells . The main studies on determination of disperse dyes are based on UV‐vis spectrophotometry with multivariate calibration, total organic carbon analysis , capillary electrophoresis, and liquid chromatography with UV or mass spectrometry detection , which all require a long preconcentration time and/or cleaning steps, as well as special procedures concerning column poisoning in chromatographic experiments.…”

The electrochemical behaviour of Disperse Red 13 dye at a glassy carbon electrode was investigated in both organic and aqueous organic mixtures. Best results were obtained in N,N‐dimethylformamide/Britton–Robinson buffer (1:1, v/v), which displays a well‐defined peak at ‐0.40 V (vs Ag/AgCl) owing to reduction of the protonated nitro group. This method can be successfully applied to the electroanalytical determination of Disperse Red 13 in a very simple and inexpensive way. All the differential pulse voltammetry parameters were optimised by using a glassy carbon electrode modified with poly(glutamic acid) films. The targeted analytical method presented a linear response from Disperse Red 13 concentrations between 2.5 × 10−7 and 3 × 10−6 mol l−1 (r = 0.997), with a detection limit of 1.5 × 10−8 mol l−1 and recoveries of 89.7–95.10% in water samples. Disperse Red 13 was successfully determined in textile industry wastewater by means of the proposed method after pre‐extraction in a solid‐phase extraction cartridge.

Polymeric fibers are one kind of trace evidence found in the crime scenes, and they play a crucial role in criminal investigation. Identification and comparison of polymeric fibers are a direct result of professional analysis. When performed properly, the analytical method used in differentiating fibers of different origins can be of high evidential value. Regular forensic examinations of synthetic fibers to determine type and subtype are based on microscopy, spectroscopy, chromatographic, and mass spectrometry. This review covers different analytical methods used in the forensic analysis and comparison of synthetic fibers.
