TL;DR: By employing a rational design approach of matching redox potentials of dye, catalysts, and reactive oxygen species (ROS), Ag-BiVO4 photo-catalysts of 2, 5 and 7wt% Ag were successfully prepared via sol-gel and UV photo-reduction methods as discussed by the authors.
Abstract: By employing a rational design approach of matching redox potentials of dye, catalysts, and reactive oxygen species (ROS), Ag-BiVO4 photo-catalysts of 2, 5 and 7 wt% Ag were successfully prepared via sol-gel and UV photo-reduction methods. The as-prepared composites over-perform existing counterparts by exhibiting excellent photocatalytic properties towards degradation of cationic methylene blue (MB, 20 min, 90.9 ± 2.4 %), brilliant green (BG, 20 min, 84.0 ± 2.7 %) and rhodamine B (RhB, 120 min, 90.5 ± 3.3 %) as well as anionic acid red 1 (AR, 60 min, 79.0 ± 2.5 %) and methyl orange (MO, 120 min, 64.9 ± 2.0 %) dyes. Furthermore, based on our novel approach of rational design, the degradation of MB dye was ascribed to photoelectrons from n-type BiVO4, while degradation of MO and AR was attributed to photo-holes from p-type Ag2O. Meanwhile, BG and RhB dyes degrade due to photoelectrons and photo-oxidation by ROS, which was confirmed by carrier scavenger experiments. Results indicate that Ag-BiVO4 oxide can be efficiently used for wastewater treatment, solar energy, water splitting, and medicine.

TL;DR: In this paper, a new method for the spectrophotometric determination of antimony in rain water is described, which includes preconcentrating Sb with surfactants (i.e., cetylpyridinium chloride (CPC) and Triton X-100 (TX-100)) into toluene and allowing the extract to react with a dye, i.e. brilliant green (BG).
Abstract: A new, simple, selective and sensitive method for the spectrophotometric determination of antimony in rain water is described It includes preconcentrating Sb with surfactants (ie cetylpyridinium chloride (CPC) and Triton X-100 (TX-100)) into toluene and allowing the extract to react with a dye, ie brilliant green (BG) The value of apparent molar absorptivity is 555 × 105 L-mol–1· cm–1 at λmax = 620 nm; the detection limit is 3 ng/mL Sb in rain water at 3-fold preconcentration

TL;DR: In this paper, a comprehensive series of mono-and di-substituted derivatives of Brilliant Green has been prepared and the various electronic absorption spectra have been determined, showing that substitution in the 2-position leads to a pronounced increase in the intensity of the long-wavelength band.
Abstract: A comprehensive series of mono- and di-substituted derivatives of Brilliant Green has been prepared and the various electronic absorption spectra have been determined. Substituents in the 3- or 4-position have little effect on the intensity of the first band, but the wavelength of maximum absorption is shifted to an extent which is linearly related to the appropriate Hammett substituent constant. Substitution in the 2-position leads to a pronounced increase in the intensity of the long-wavelength band.
