Abstract

A novel adsorbent, triazine core-containing resin (ODA-TRIAZ) was successfully, synthesized and employed for ultrahigh adsorptive removal of malachite green dye (MG) from water. The ODA-TRIAZ was found to be mesoporous in nature possessing abundant aromatic and amine functional groups that favors effective aqueous phase adsorption. Rapid equilibrium attainment for MG uptake was achieved that resulted in high maximum adsorption capacity (qmax) of 784.789 mg g−1 for MG at pH 8–10 and 25 °C, a significant improvement compared with similar reported resin-based adsorbents. Pseudo-second-order model well described the MG uptake kinetics while both Freundlich and Langmuir models describe the MG equilibrium behaviors. The mechanism of MG uptake was predominantly via multilayered adsorption mechanism with involvement of π–π stacking or hydrophobic interaction and hydrogen bonding that increases with increases in temperature and initial pH. The ODA-TRIAZ high reusability potentials with up to 95% performance after 5 consecutive adsorption–desorption cycles, an indication of been promising adsorbent for real water and wastewater treatment.
