This paper analyzes the adsorption of two potential toxic dyes, i.e. methylene blue (MB) and crystal violet (CV) onto Bauhinia forficata residual fruit powder (BFRFP) as a new promising adsorbent. The experiments aimed at retrievement data are carried out T = 298–328 K coupled with an adsorbent characterization to better highlight MB CV dyes mechanism. capacity saturation (ACS) varies from 181....
This study investigated the development of a novel approach to surface characterization of drug polymorphism and the extension of the capabilities of this method to perform 'real time' in situ measurements. This was achieved using diffuse reflectance visible (DRV) spectroscopy and dye deposition, using the pH sensitive dye, thymol blue (TB). Two polymorphs, SFN-β and SFN-γ, of the drug substanc...
Microfluidic dye lasers (MDL) have recently emerged as promising candidates to facilitate the fusion of optics and fluidics at the microscale. Their primary advantage over gas or solid state lasers is the inherent wavelength tunabililty which can be achieved by changing the type of dye used, the dye concentration, or the host solution. Here, we report on the design and characterization of a MDL...
The response times of pressure-sensitive particles to passing shockwaves were measured to investigate their ability to accurately determine pressure changes in unsteady flows. The particles tested were loaded with novel pressure-sensitive dyes such as Pt (II) meso-tetra(pentafluorophenyl)porphine, Pt(II) octaethylporphine, bis(3,5-difluoro-2-(2-pyridyl)phenyl-(2-carboxypyridyl))iridium III, and...
An efficient synthetic protocol to functionalize the cyanoacrylic acid anchoring group of commercially available MK-2 dye with a highly water-stable hydroxamate anchoring group is described. Extensive characterization of this hydroxamate-modified dye (MK-2HA) reveals that the modification does not affect its favorable optoelectronic properties. Dye-sensitized solar cells (DSSCs) prepared with t...
The physicochemical characterization of the textile industry effluent collected from Oswal Textile Industries, Ludhiana (Punjab.) India has been carried out and the results showed that the temperature (40°C), pH (8.00), Biological Oxygen Demand (260 mgl –1 ), Chemical Oxygen Demand (790 mgl –1 ), Total Suspended Solids (2000 mgl –1 ), Total Dissolved Solids (7000 mgl –1 and colour over the pres...

In this study, ZnO nanoparticles fixed on glass plates were employed as photocatalysts for the degradation of Acid Red 88 (AR88) dye in aquatic solution. ZnO nanoparticles were synthesized through coprecipitation method and fixed on glass plates. X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques were used for characterization of nanoparticle samples. A batch reactor equi...
The ability of two varieties (hard and soft) of almond peels, as inexpensive sorbents for the removal of bezanyl red (acid dye) from synthetic aqueous solutions has been studied. After their characterization by different techniques, (elemental analysis, biochemical analysis, IR spectroscopy, thermogravimetric analysis, scanning electron microscopy and mercury porosimetry), the dye sorption kine...
Dye wastewater produced in textile industries is a warning issue that threatens the environment due to discharge into waterway. This study reviewed adsorption of Methylene Blue (MB), as toxic dye, onto diatomite adsorbent. A series chemical modifications were examined by impregnating various acidic and basic solutions obtain most active sample with highest capacity. Both raw (RD) modified (MD) ...
