Abstract

The azo dye and plant-derived sorbent system was investigated in this paper. Direct Orange 26 azo dye was acquired from Boruta-Zachem Kolor Sp. z o.o. Chemically modified granulated corncobs obtained from Chipsi Mais Germany were used as the biosorbent. The changes in the dye and sorbent concentrations with time were measured and used for further calculations. The experiments were carried out in a laboratory fixed bed column. Breakthrough curves were plotted for different initial concentrations, volumetric flow rates and bed heights. Sorption dynamics was described by a model presented in the literature. It was demonstrated that Infrared analysis of the system allows to determine the nature of the dye-sorbent bond. It was found that corncobs can be used as a promising sorbent material.
