Decolorization of azo dyes in bioelectrochemical systems.

Yang Mu et al.

Environmental science & technology, 43(13), 5137-5143 (2009-08-14)

Azo dyes are ubiquitously used in the textile industry. These dyes need to be removed from the effluent prior to discharge to sewage due to their intense color and toxicity. In this study we investigated the use of a bioelectrochemical

Structural and temperature effects in the high-performance liquid chromatographic enantioseparation of 1-(alpha-aminobenzyl)-2-naphthol and 2-(alpha-aminobenzyl)-1-naphthol analogs.

Anita Sztojkov-Ivanov et al.

Journal of separation science, 28(18), 2505-2510 (2006-01-13)

The enantiomers of 1-(alpha-aminobenzyl)-2-naphthol and 2-(alpha-aminobenzyl)-1-naphthol analogs were separated isothermally on a cellulose-tris-3,5-dimethylphenyl carbamate-based chiral stationary phase (Chiralcel OD-H), at 10 degrees C increments in the range of 5-35 degrees C, using n-hexane/2-propanol/diethylamine as mobile phase. The mobile phase composition
