In the present research, zeolite is used for removal of toxic Congo red dye from water solution. The effects different operating conditions such as hydrogen potential (pH), contact time (time), dose (D), initial concentration (C0), and ionic strength (I) are investigated adsorption under batch mode. It was found that process greatly affected by pH efficiency decreased 97.68 to 5.22% when varied...

Textile dyeing is considered to be one of the major industrial sources of high rates of organic and aromatic compounds. Conversely, these compounds have become a significant environmental problem. Many methods have been investigated for color removal from dye-containing wastewater. In this research, the efficiency of the electrocoagulation (EC) process with aluminum electrodes in the removal of...

Titanium dioxide (TiO2) and Fe3O4 magnetite particles were coated on spherical Kissirises; glucose oxidase (GOx) enzyme was immobilized on Kissiris/Fe3O4/TiO2 by physical adsorption. This catalyst was analyzed by a scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and energy dispersive X-ray (EDX) measurements. The performance of the prepared biocatalyst in the...

Present work investigates the capability of oxidative treatment process in the presence of nano silver doped on silicate particles for decolorization of a widely used azo dye, C.I. Direct Blue 129 (DB129) in water samples. Solutions with initial concentration of 20 mgL-1 of dye, within the range of generic concentration in textile wastewaters, were treated under ambient conditions of initial pH...

Low-cost grapefruit peel (Agricultural Waste) was used for removal of reactive blue19 dye fromaqueous solutions. The process was studied as a function of contact time, initial dye concentration andpH. Adsorption process was attained to the equilibrium within 45 min for initial dye concentrations of 50,75, and 100 mg L-1. An acidic medium was the optimum condition for adsorption of dye at roomte...

This study investigates the adsorption behavior of Reactive Black 5 (RB) and Reactive Yellow 176 (RY) from aqueous solution on coal fly ash (FA-CO), HCl-treated coal fly ash (TFA-HCl), and biomass fly ash (FA-BM). In preliminary study, the FA-BM showed the greatest dye adsorption capacity of both dyes, compared to FA-CO and TFA-HCl. Hence only for the FA-BM, the effects of various experiment pa...
