In this way, it was aimed both to evaluate the wastes and to prevent environmental pollution with materials that are cheaper and easier to obtain. The structure and surface properties of wood waste and coal samples crushed and ground to -75 µm size and used as adsorbent were investigated by XRD, SEM and BET analyses. In addition, samples have been characterized by elemental, ash, moisture, volatile matter and fixed carbon analyses. In the experiments, methylene blue (MM) with the formulation of C<inf>16</inf>H<inf>18</inf>CIN<inf>3</inf>S.xH<inf>2</inf>O was used. The effects of temperature, mixing time and concentration parameters on MM adsorption were investigated. Langmuir isotherms were created for different temperatures at optimum concentrations. As a result, it has been revealed that lignite coal and wood waste can be used as adsorbent. A 10 ppm MM for lignite coal and 3 ppm MM for wood waste were determined to be ideal concentrations for adsorption. © 2022 Elsevier B.V., All rights reserved.trinfo:eu-repo/semantics/openAccessAdsorptionLignite CoalMethylene BlueWood WasteAromatic CompoundsIsothermsLigniteParticle Size AnalysisWood%MoistureCoal SampleDyes AdsorptionsEnvironmental PollutionsGasification PlantsLignite CoalMethylene BlueParticle-BoardWaste SamplesXrdAdsorptionAbsorptionAdsorptionChemical ReactionCoalConcentration (Composition)Detection MethodDyePollutant RemovalAromatic CompoundsGebzeKocaeli [Turkey]SivasTurkeyArticle10.30797/madencilik.8437722-s2.0-85122764321
