Abstract:
The present work deals with the biosorption of chromium (VI) by Spruce sawdust within a column of laboratory scale. Spruce sawdust is a waste produced by furniture industry and may be used as a low-cost potential adsorbent, for the removal of dyes and heavy metals, amongst them the most toxic chromium (VI), from aqueous solutions. Seven different kinetic equations, namely, Bohart–Adams, Thomas, Yoon–Nelson, Clark, Modified dose–response, Bed depth-service time (BDST) and Wolborska models were applied to the experimental data to predict the breakthrough curve and to determine the characteristic parameters of the column, which are of critical importance for designing/developing large–scale column. The results indicate that the Modified dose–response (MDR) model provides the most satisfactory fitting to experimental data.
