This article describes the use of a power plant waste-Bottom Ash, as effective adsorbent for the removal of toxic Azo dyes Carmoisine and Chrysoidine Y from their aqueous solution. The paper incorporates comparative study and discussion of the adsorption characteristics of these dyes on the economically effective adsorbent with special emphasis on the effects of time and temperature. The charac...

Recently, iron nanoparticles are increasingly being tested as adsorbents for various types of organic and inorganic pollutants. In this study, nanoparticles of zero-valent iron (NZVI) synthesized under atmospheric conditions were employed for the removal of Ba(2+) ions in a concentration range 10(-3) to 10(-6) M. Throughout the study, (133)Ba was used as a tracer to study the effects of time, c...

Electron beam irradiated sheep wool dosed (0–410) kGy showing good adsorption properties was tested for Cr(III) and Co(II) of higher concentrations. Fitting to ten isotherm models examined as follows: Langmuir, Freundlich, Dubinin-Radushkevich, Temkin, Flory-Huggins, Halsey, Harkins-Jura, Jovanovic, Elovich Redlich-Peterson. Both cations being Lewis acids generate complex salts, such carboxylat...

Electrocoagulation (EC) was used for the removal of anthraquinone dye, Alizarin Red S (ARS) from aqueous solution. The process was carried out in a batch electrochemical cell with Al electrodes in a monopolar connection. The effects of some important parameters such as current density, pH, temperature and initial dye concentration, on the process were investigated. Equilibrium was attained afte...

This study was investigation employed the batch adsorption method using Bardakçı Clay/Van as an adsorbent to remove crystal violent, a cationic dye from aqueous solution. The effects of pH, amount, interaction time and concentration were investigated determine optimal conditions. conditions determined be pH=6, 0.6 g reached equilibrium at 25th minute. isotherm Langmuir, Freundlich Dubinin–Radus...

Adsorption of ammonia from anaerobic digester effluent by magnetically modified zeolite (MMZ) has been investigated using a batch technique and comparison of adsorption isotherm equations. Adsorption isotherm models were utilized to describe the equilibrium isotherms and the isotherm constants were calculated. The sorption of ammonia follows Langmuir, Freundlich and Dubinin-Radushkevich (D-R) m...

The paper presents our new results about efficiency of wastes based on hydrolyzed polyacrylonitrile textile fibers (HPAN) as sorbents in removal of some dyes from textile effluents. The effect of some experimental variables such as initial dye concentration, sorbent mass, pH, temperature, and contact time were investigated. The sorbent dye sorption systems are described using Freundlich, Langmu...

Activated carbon prepared from coir pith (ZnCPC) using ZnCl2 was investigated to find the feasibility of its application for removal of 2,4–dichlorophenol (2,4-DCP) in aqueous solution through adsorption process. Batch mode kinetics and isotherm studies were carried out to evaluate the effects of contact time, initial concentration, adsorbent dose, pH, and temperature. Lagergren, Second order, ...
