Description: •Complexes of carboxy-methylated lignin with Al and Mn were used as adsorbents.•The optimum adsorption conditions were achieved at pH 2 and 298K.•Maximum adsorption capacities are 73.52mgg−1 (CML-Al) and 55.16mgg−1 (CML-Mn).•CML-Al could remove ca. 95.83% of dye-contaminated industrial effluents.•CML-Al and CML-Mn are effective for treatment of simulated dye-house effluents. A macromolecule, CML, was obtained by purifying and carboxy-methylating the lignin generated from acid hydrolysis of sugarcane bagasse during bioethanol production from biomass. The CMLs complexed with Al3+ (CML-Al) and Mn2+ (CML-Mn) were utilised for the removal of a textile dye, Procion Blue MX-R (PB), from aqueous solutions. CML-Al and CML-Mn were characterised using Fourier transform infrared spectroscopy (FTIR), scanning differential calorimetry (SDC), scanning electron microscopy (SEM) and pHPZC. The established optimum pH and contact time were 2.0 and 5h, respectively. The kinetic and equilibrium data fit into the general order kinetic model and Liu isotherm model, respectively. The CML-Al and CML-Mn have respective values of maximum adsorption capacities of 73.52 and 55.16mgg−1 at 298K. Four cycles of adsorption/desorption experiments were performed attaining regenerations of up to 98.33% (CML-Al) and 98.08% (CML-Mn) from dye-loaded adsorbents, using 50% acetone+50% of 0.05molL−1 NaOH. The CML-Al removed ca. 93.97% while CML-Mn removed ca. 75.91% of simulated dye house effluents.
