New sulfa drugs azo dyes (HL1, HL2, HL3, HL4 and HL5) were prepared by the coupling of 6-formyl-7-hydroxy-5-methoxy-2-methylbenzopyran-4-one with the sulfa drugs (sulfadiazine, sulfapyridine, sulfamethoxazole, sulfadimidine, sulfathiazole). The five prepa... see more

A series of monoazo disperse dyes were synthesized by coupling diazotized 4-amino-N-dodecyl-1,8-naphthalimide with N,N-dialkyl anilines and naphthol derivatives. The synthesized intermediates and the dyes were charac­terized using FTIR, 1H-NMR, 13C-NMR, m... see more

Textile industry contributes the most disposals of synthetic dyes, and about 40% of textile dyes has been generating high amount of colored wastewater. Polycyclic aromatic hydrocarbons (PAHs), such as phenanthrene, is a group of organic compounds, that st... see more

Water pollution by dyes represents from dyestuff industry becomes an environmental concern. Finding new isolates capable of decolorizing these dyes is important. The study aimed to assess the new isolates of white-rot fungi (WRF) as decolorizing agent of ... see more

The Adsorptive Cathodic Stripping Voltammetry (ACSV - differential pulse) proved to be an efficient method in the separation and quantification of two reactive textile dyes, Procion Yellow (PY) and Procion Red (PR), each containing two azo groups as chrom... see more

Azo dyes are recalcitrant pollutants present in effluents of several industries. Due to their chemical stability, their degradation efficiency is not satisfactory by con­ventional technologies. Advanced oxidation processes, such as Fenton, can be applied ... see more

This study investigated the use of ferrate – hypochlorite solution or solid Ca(OCl)2 as treatment options to remove color and COD from solutions of the synthetic organic dyes: Reactive blue 19, Allura red and Reactive black 5. It was found that doses arou... see more

This paper deals with the in-situ electrochemical oxidation of Reactive Black 5 (RB-5), Reactive Blue 19 (RB-19) and Allura Red AC (AR-AC), using commercial steel wool as electrodes. At the optimal conditions (18 V and NaOH 0.33M), the decolorization of R... see more
