Four selected azo dyes (acid orange 6, acid orange 7, methyl orange and methyl red) were completely decolourised in the presence of anaerobic granular sludge, while only methyl red was degraded in aerobic conditions using a conventional activated sludge. Additional experiments with culture broth devoid of cells showed that anaerobic decolourisation of azo dyes was performed by extracellular red...

Ruthenium nanoparticle tris(2,2'-bipyridyl)ruthenium(II) bis(hexafluorophosphate) (Ru(bpy)3(PF6)2, RuNP) was self-assembled on polystyrene (PS) electrospun microfibers. The formation of RuNP is attributed to the sulfonated PS (SPS) microfibers' high adsorptive capability of 94% for Ru(bpy)3(2+), as well as the strong interaction between the Ru(bpy)3(2+) and ionic liquid (1-butyl-3-methylimidazo...

The cy-naphthol (Molisch) reaction for sugars has been neglected as a possible basis for a quantitative method. As a ring test, the only form in which it is ever described, it is very crude. The violet colors produced at the surface of contact of concentrated sulfuric acid and a sugar solution containing cr-naphthol are often obscured by charring. The lack of control of the concentration of sug...

In the title compound, C(10)H(9)NO, the amino and the hydr-oxy groups act both as a single donor and a single acceptor in hydrogen bonding. In the crystal, mol-ecules are connected via chains of inter-molecular ⋯N-H⋯O-H⋯ inter-actions, forming a two-dimensional polymeric structure resembling the hydrogen-bonded mol-ecular assembly found in the crystal structure of naphthalene-1,5-diol. Within t...

Insects from a variety of Orders have been shown to detoxify phenols by conjugation with glucose and this mechanism has been suggested as a systematic biochemical characteristic of insects (Smith, 1955a). The phenols may be foreign compounds or may be those formed in the normal course of metabolism (Smith, 1955b, 1964; Kent & Brunet, 1959; Stay & Roth, 1962; Butenandt, Biekert, Kubler & Linzen,...
