TL;DR: The new RRS method was applied to the direct determination of traces of cadmium in pure zinc and synthetic water samples and showed significant enhancement of resonance Rayleigh scattering (RRS) intensity and the appearance of new R RS spectra.
Abstract: In dilute phosphoric acid solution, cadmium (II) reacts with a large excess of I– to form [CdI4]2– which reacts further with basic triphenylmethane dyes such as crystal violet (CV), ethyl violet (EV), methyl violet (MV), brilliant green (BG) or malachite green (MG) to form an ion-association complex. This results in a significant enhancement of resonance Rayleigh scattering (RRS) intensity and the appearance of new RRS spectra. The characteristics of RRS spectra of the ion-association complexes, the influencing factors and the optimum conditions of these reactions have been investigated. The intensity of RRS is directly proportional to the concentration of cadmium from ¶0 to 60 ng mL–1 for EV and MV systems, 0 to 80 ng mL–1 for CV system, and 0 to 100 ng mL–1 for BG and MG systems. The methods exhibit high sensitivities and the detection limits for cadmium are between 0.35 and 2.00 ng mL–1 depending on the different reaction systems. The new RRS method was applied to the direct determination of traces of cadmium in pure zinc and synthetic water samples.

TL;DR: In this paper, the most common organic dyes used to color agates in the Brazilian industries are Rhodamine B, Crystal Violet, and Brilliant Green, and the environmental implications of the treatment procedure carried out by the industries are discussed.
Abstract: The most common organic dyes used to color agates in the Brazilian industries are Rhodamine B, Crystal Violet, and Brilliant Green. Washing procedures carried out after the staining process release some amounts of these compounds given an undesirable color to the water. The aim of this work is to report the characteristics of the wastewaters and describe the treatment procedures used by the industries. In addition, studies of photodegradation and chemical oxidation for each one of the colorants were conducted at laboratory scale. The results showed that Rhodamine B is more resistant to photodegradation and chlorine oxidation than Crystal Violet and Brilliant Green. The environmental implications of the treatment procedure carried out by the industries are discussed.

TL;DR: A total of 448 clinical isolates and seven reference strains of Candida species were tested for their susceptibility to a group of dyes and chemicals and resistogram patterns obtained were found to be specific for each species.
Abstract: A total of 448 clinical isolates and seven reference strains of Candida species were tested for their susceptibility to a group of dyes and chemicals All strains were also identified by conventional methods The chemicals/dyes used in the disc diffusion tests were brilliant green, janus green, cycloheximide, fast green, rhodamine 6 G, ethidium bromide and 2, 3, 5 triphenyl tetrazolium chloride Sensitivity to the chemicals was coded by a seven-figure code Resistogram patterns obtained were found to be specific for each species The disc diffusion test was found to be inexpensive, quick and gave reliable results within 18 h

TL;DR: In this paper, the ground state recovery dynamics of triphenylmethane dyes, brilliant green and malachite green, were studied by a single wavelength pump-probe spectroscopy at 635 nm with a time-resolution of 33 fs.
Abstract: We have studied ground state recovery dynamics of triphenylmethane dyes, brilliant green and malachite green, by a single wavelength pump-probe spectroscopy at 635 nm with a time-resolution of 33 fs. The recovery of the ground state dependeded on solvent viscosity and also on solute molecular size. We observed a plateau or a rise component in the signal which indicates an intermediate state. The rise time also showed solvent viscosity dependence even in the ultrafast time domain, although no solute dependence was observed. It is suggested that the lack of solute dependece indicates that only small conformational change is involved in the initial process.

TL;DR: Sticking-plaster tape as discussed by the authors is a tape made from hygroscopic atraumatic material (e.g. gauze insertion) impregnated with antiseptic substance solution (0.02-0.6% furacillin, 0.08-2.4% synthomycin, 0.,011- 0.1% brilliant green) is fixed.
Abstract: FIELD: pharmaceutical industry. SUBSTANCE: sticking-plaster consists of sticking-plaster tape, on the sticking-side surface of which hygroscopic atraumatic material (e.g. gauze insertion) impregnated with antiseptic substance solution (0.02- 0.6% furacillin, 0.08-2.4% synthomycin, 0.011-0.1% brilliant green) is fixed. Sticking-plaster can be used in treating cutaneous diseases and microtraumas. EFFECT: improved therapeutic effect and stabilized controlled parameters on storage longer than 3 years. 5 cl, 1 tbl
