TEXTILE DYES
Abstract Azo dyes are of environmental concern due to their degradation products, widespread use, and low‐removal rate during conventional treatment. Their toxic properties related the nature position substituents with respect aromatic rings amino nitrogen atom. The Disperse Red 1 13 were tested for Salmonella mutagenicity, cell viability by annexin V, propidium iodide in HepG2 aquatic toxicity assays using daphnids. Both positive assay, suggestion was made that these compounds induce mainly...
Azo dyes constitute the largest class of synthetic dyes. Following oral exposure, these can be reduced to aromatic amines by intestinal microflora or liver enzymes. This work identified products formed after oxidation and reduction dye Disperse Red 1, simulating hepatic biotransformation evaluated mutagenic potential resultant solution. Controlled electrolysis was carried out on solution using a Potentiostat/Galvanostat. HPLC-DAD GC/MS were used determine generated oxidation/reduction...
Photoelectrocatalytic oxidation of 0.1mM Bisphenol A (BPA) leads to 100% degradation monitored by liquid chromatography with diode array optical detection (limit 1microgL(-1)) and TOC removal. Optimum performance was obtained using TiO(2) nanotubular (NTA) electrodes, grown anodization Ti foil in 0.25wt.% NH(4)F a mixture glycerol water (ratio 90:10vol.%) an applied voltage 20V for 50h. The effects supporting electrolyte, pH, bias potential BPA concentration were evaluated as their effect on...
