Abstract

In the present work the adsorption equilibriubm data of the binary combinations of three basic dyes, namely, Basic Blue 69, Basic Red 22 and Basic Yellow 21, onto activated carbon are obtained. The extended empirical Freundlich isotherm for binary systems was used, together with an additional assumption. Compared with previous works, this modification leads to a procedure that requires much less experimental and mathematical work. Through more restricted, the present method has been found to yield accurate results.
