Decolorization percentage of real textile wastewater treated with control chitosan-beads (A) and magnetic-chitosan gel beads (B) using various concentrations (0.25–1.5 g/l) at different time intervals (30–150 min) under the same incubation conditions. (C) Relative decolorization percentage of the repeated treatment cycles using MchiBs. The setup performed under the optimal conditions. The washed beads were used for the subsequent cycles and the decolorization percentage was computed in relation to the 1st treatment cycle.
