Abstract
The adsorption of three basic dyes from water onto bagasse pith has been studied. The dyes used were Basic Blue 3, Basic Red 22 and Basic Yellow 21 and single and multicomponent equilibrium isotherms were determined. The three single, three binary and one ternary system isotherms were analysed. Predictive and correlative techniques have been developed and used to produce theoretical multicomponent equilibrium isotherm data which are then quantitatively compared with experimental data. This procedure enables a qualitative and quantitative appraisal of the various equilibrium models to be compared. The models used include the Langmuir and Redlich-Peterson isotherms in extended and modified forms; the modified form incorporates an interaction factor to account for multisolute phenomena. An extended Freundlich isotherm yielded the most accurate method of predicting experimental binary system equilibrium data.
