Slag has also been used for dyes removal [274,275]. The utilization
of treated basic oxygen furnace slag (BOF slag) was successfully
carried out to remove three synthetic textile dyes (reactive blue
19 (RB19), reactive black 5 (RB5) and reactive red 120 (RR120))
from aqueous solutions by Xue et al. [275]. In the batch system,
the maximum dye uptake on acid-treated BOF slag adsorbent
was observed at pH 2.0, and the maximum RB5, RB19 and RR120
uptake capacities (at 500 mg/L dye concentration) were 76, 60 and
55 mg/g, respectively. Adsorption kinetic process followed firstorder
kinetic model.
