Abstract Lignin is a major by-product problem for the pulp and paper industry. Inour previous work, lignin was successfully separated from alkali lignin wastewater usingiron (III) trimesic (Fe-BTC). This separationresulted in three layers: supernatant, lignin sludge, and Fe-BTC powder. In this study, the lignin separated by Fe-BTC (LSF)was expected to be used as an adsorbent for reactive red-120 dye (RR-120) removal.The LSF morphology was characterized by scanning electron microscope and energy dispersive X-ray spectrometer(SEM-EDS),the specific surface area was analyzed by Brunauer-Emmett-Teller (BET)method,and the functional groups were investigatedby Fourier transform infrared (FTIR)spectrometer. The removal performance of LSF over RR-120 was approximately 35% in 60 min. The maximum adsorption capacity of LSF for RR-120 was found to be 10.363mg/g. The adsorption kinetic of RR-120 removal fitted well with the pseudo-second-order kinetic model. The adsorption isotherm model of LSF also fitted with the Langmuir isotherm model. This research suggests the high potentialof LSF as a lignin-based adsorbent agent for RR-120 removal in water.
