TL;DR: In this paper, the ultrasound-assisted removal of Auramine-O (AO) dye from aqueous solutions using ZnS:Cu nanoparticles loaded on activated carbon (ZnS-Cu-NP-AC) as an adsorbent was investigated.
Abstract: This research is focused on the ultrasound-assisted removal of Auramine-O (AO) dye from aqueous solutions using ZnS:Cu nanoparticles loaded on activated carbon (ZnS:Cu-NP-AC) as an adsorbent. ZnS:Cu nanoparticles were synthesized and characterized using FESEM (Field-Emission Scanning Electron Microscopy) and XRD (X-Ray Diffraction) analysis. The experiments were designed by response surface methodology. A quadratic model was used to predict the variables. Analysis of variance was used for investigation of variables and interaction between them. High F-value (48.91), very low P-value (<0.00001), non-significant lack of fit, and the determination coefficient (R2 = 0.977) demonstrate good correlation between experimental and predicted values of the response. The highest removal percent attained was 99.76%, and the optimum parameters achieved are: adsorbent amount (0.02 g), initial dye concentration (20 mg L−1), sonication time (3 min) and pH = 7. Adsorption processes of AO by ZnS:Cu-NP-AC could be well described by a Langmuir isotherm and a pseudo-second-order kinetic model. The maximum adsorption capacity of AO by ZnS:Cu-NP-AC was determined as 183.15 mg g−1, suggesting a highly promising potential for ZnS:Cu-NP-AC to be used as a new adsorbent.

TL;DR: Copper oxide nanoparticles loaded on activated carbon (CuO-NPs-AC) were prepared and fully analyzed and characterized with FE-SEM, XRD and FT-IR and used for simultaneous ultrasound-assisted adsorption of brilliant green (BG), auramine O (AO), methylene blue (MB) and eosin yellow (EY) dyes.

TL;DR: In this article, the effect of variables such as adsorbent dosage, sonication time, initial concentration of MB, and initial concentrations of AO on the removal percentages of MB and AO dyes were simultaneously investigated by central composite design (CCD) under response surface methodology (RSM) while pH was optimized separately.
Abstract: The focus of this research is on the rapid ultrasound-assisted removal of Methylene blue (MB) and Auramine-O (AO) dyes from aqueous solutions using ZnS:Cu nanoparticles loaded on activated carbon (ZnS:Cu-NP-AC) as a low cost and environmental friendly adsorbent. The adsorbent was characterized by FE-SEM, FTIR and XRD. The effect of variables such as adsorbent dosage, sonication time, initial concentration of MB, and initial concentration of AO on the removal percentages of MB and AO dyes were simultaneously investigated by central composite design (CCD) under response surface methodology (RSM) while pH was optimized separately. It was shown that the adsorption of AO and MB follows the pseudo-second-order rate equation, while the Langmuir model explains equilibrium data. A small amount of the adsorbent was able to remove more than 99.5% of both dyes rapidly with high adsorption capacity in single component system (106.9 mg/g for MB, and 94.2 mg/g for AO) and in binary-component system (51.7 mg/g for MB, and 38.1 mg/g for AO). It is worth to note that the optimum adsorption of MB and AO dyes occurred at neutral pH, which is an advantage of our work.

TL;DR: The photocatalytic degradation of five anionic, eight cationic and three solvent dyes using combustion-synthesized nano-TiO( 2) (CS TiO(2)) and commercial Degussa P-25 TiO (2) (DP-25) were evaluated to determine the effect of the functional group in the dye.

TL;DR: Auramine O (AuO) was solubilized in a reversed micellar core (water pool) to determine the microviscosity of AuO as discussed by the authors, which was localized at the vicinity of the water/surfactant interface owing to electrostatic association between the polar head groups in AOT and AuO.
Abstract: Auramine O (AuO), the fluorescence quantum yield (Φ f ) of which increases with increasing solvent viscosity, was solubilized in Aerosol-OT (AOT) reversed micellar core (water pool) to determine the microviscosity (η w ). This probe is localized at the vicinity of the water/surfactant interface owing to electrostatic association between the polar head groups in AOT and AuO. The microviscosities were determined rapidly as a function of R w (=[H 2 O]/[AOT]) by measuring the Φ f of AuO solubilized in the water pool
