Study the adsorption of basic blue and neutral red dye from aqueous solution by zeolite clay surface

Abstract EN

In this study, the removal of cationic dye basic blue and neutral red dye used in the aqueous solutions with zeolite was investigated as a function of ionic strength, pH and temperature.

Adsorption process was attained to the equilibrium within 1 h.

The adsorbed amount of two dyes basic blue and neutral red dye increased with increasing ionic strength, but decreased with increasing temperature and pH.

Adsorption of cationic dye basic blue and neutral red dye was investigated by using uv-visible technique.

The Freundlich and Dubinin-Rasdushkevich (D-R) isotherm equations were applied to the data and values of parameters of these isotherm equations were calculated.

The mean energy of adsorption E, was also calculated from the adsorption energy constant Keng.

It’s Value determined from the D-R isotherm equation.

Finally thermodynamic functions ∆G, ∆S and ∆H, were calculated by using Freundlich isotherm.
