Adsorption of chromium (VI) ions onto carbon black - Langmuir isotherms

Many models exist for describing the experimental results of batch adsorption which are used to study equilibrium, kinetics, and mechanisms of adsorption. Equilibrium results, i.e. the adsorption isotherm, are theoretically interpreted by checking the applicability of a group of model isotherms. In this work, equilibrium studies were carried out for the adsorption of Cr(VI) onto a commercial carbon black as an adsorbent. The experimental data were fitted to the different types of Langmuir isotherms by linear method. The characteristic parameters of each isotherms and related coefficients of determination (R2) have been determined.
