Voltammetry of Tetra-alkyl Ammonium Salts at Platinum in Sulphur Dioxide Solution: Oxidation of the Halides*
The polarographic or voltammetric behaviour of a selected group of tetra-alkyl ammonium halides and related compounds in liquid sulphur dioxide was investigated, using a stationary disk platinum indicating micro-electrode and a silver/silver-bromide reference electrode withcompensation for the IR drop of the solution. The electrochemical oxidation-reduction patterns are characteristic of the na...
متن کاملAptamers switch on fluorescence of triphenylmethane dyes.
MG and SRB aptamers, which are short RNA sequences originally selected only for binding to malachite green or sulforhodamine B, can greatly enhance the fluorescence of normally nonfluorescent triphenylmethane dyes. MG aptamer enhances the quantum yields of malachite green (MG) and a novel rigidized derivative, indolinyl malachite green (IMG) by >2000-fold. SRB aptamer brightens patent blue V an...
متن کاملRemoval of Triphenylmethane Dyes by Bacterial Consortium
A new consortium of four bacterial isolates (Agrobacterium radiobacter; Bacillus spp.; Sphingomonas paucimobilis, and Aeromonas hydrophila)-(CM-4) was used to degrade and to decolorize triphenylmethane dyes. All bacteria were isolated from activated sludge extracted from a wastewater treatment station of a dyeing industry plant. Individual bacterial isolates exhibited a remarkable color-removal...
متن کاملInterferometric determination of the refractive index of liquid sulphur dioxide
The absolute refractive index of liquid sulphur dioxide (SO2) was determined with an uncertainty of ±0.0007 with the help of a Michelson interferometer and a computer-controlled rotatory stage supporting a rectangular fused silica cell, containing the liquid. The measurements were performed at temperatures around 20 ◦C for the laser line wavelengths 632.8, 514.5 and 488.0 nm. The experimental d...
متن کاملThe role of sulphur, sulphide and reducible dyes in the enzymic oxidation of cysteamine to hypotaurine.
1. Cysteamine is oxidized to hypotaurine by an enzyme extracted from horse kidney, with sulphur or sulphide acting as a cofactor. It has been now found that, when the enzyme is omitted, sulphur and sulphide are able to catalyse the oxidation of cysteamine to cystamine by molecular oxygen. 2. Methylene blue may be used in catalytic amounts as a cofactor in the enzymic oxidation of cysteamine to ...
