摘要: Abstract A complex Remazol dye effluent, comprised of four reactive dyes and auxiliary chemicals, was decolorized using SPS-200 (sawdust-based) SPC-100 (coal-based) activated carbons. detailed characterization revealed that the pore diameter carbon played an important role in adsorption. The solution pH had no significant effect on adsorption capacity range 2–10.7. According to Langmuir model, maximum uptakes were 415.4, 510.3, 368.5 453.0 mg g −1 for Reactive Black 5 (RB5), Orange 16 (RO16), Brilliant Blue R (RBBR) Violet 5R (RBV), respectively. Conversely, those slightly lower, at 150.8, 197.4, 178.3 201.1 mg g RB5, RO16, RBBR RBV, In case exhibited a decolorization efficiency 100% under unadjusted conditions 10.7, compared 52% SPC-100.
