Investigation of the Factors Affecting the Removal of an Acid Dye from Aqueous Solution by Adsorption Using Bentonite and Sepiolite
The effects of some factors on the adsorption of an Acid dye (Acid Blue 193, AB 193) from aqueous solution onto bentonite and sepiolite samples were studied.These factors were saturation of the samples with cations (Na + and Ca 2+ ), the pH and the ionic strength of the dye hemi procharger solution.The Langmuir and Freundlich adsorption models were
