background and purpose: generated dye wastewater by the textile industry is usually toxic, non-biodegradable and resistant in the environment. eggshell is one of the inexpensive material and for the reason the vesicular structures can be used as a proper adsorbent for pollutants removal. the aim of this study is to investigate the efficiency of eggshell for removal of acid orange 2 dye from aqu...

we demonstrate that photothermal deflection spectroscopy can be used to measure velocity distributions in dye jets. such measurements are useful in determining the quality of flow in dye jets, the quality of jets is very important for a stable and naanow linewidth operation of dye lasers

in the present study, hydrilla verticillata biomass was investigated as a novel biosorbent for the uptake of basic dye malachite green from its aqueous solution. kinetic and equilibrium studies were carried out in batch process. batch adsorption experiments were conducted to study the effect of ph, temperature, sorbent dosage, initial dye concentration, and contact time for the removal malachit...

nanocrystalline titanium (iv) oxide paste has been deposited on fluorine doped tin oxide glass substrate by the blade method. the deposited film was subjected to thermal treatment to obtain an electrode foe a photo-electrochemical cell. the electrode was sensitized with prophyrin dye which was a local dye extracted from carica papaya leaves. avaspec 2.1 spectrophotometer was used to obtain the ...

ZnO and TiO2 nanoparticles wereimpregnated with merbromin dye and used as modified photocatalysts for degradation of phenol. Dye-modified ZnO and TiO2 showed significantly higher photocatalytic activity than neat ZnO and TiO2 under visible light illumination. Moreover, the prepared dye-modified ZnO showed superior photocatalytic efficiency in degrad...
