Abstract:
Batch sorption experiments were carried out to remove reactive dye
Brilliant Red HE-3B from its aqueous solutions using industrial waste ash
and materials based on ash as a low cost sorbent. To establish the most
suited type of materials to be used as sorbent for this dye, the effect of
various experimental parameters such as solution pH, initial dye
concentration, sorbent dose and type of sorbent were investigated. The
results of this study show that all of the tested materials have a limited
capacity for dye molecules uptake but we also observed that sorbent namely
Ads 4 present the best values from the sorption capacity of sorption. The
percent of reactive dye Brilliant Red HE-3B sorption has a maximum at pH
2.0 - 5.0 and increases with the increase of sorbent dose, temperature and
decreases with increasing initial concentration of solution.
