In this study, the removal of Mn2+ ions from waters by the adsorption method using ash obtained from a treatment plant sludge burning unit, which is treatment plant waste and mostly disposed of in a landfill, was investigated. By determining the most suitable conditions for adsorption, adsorption kinetics, isotherms, and thermodynamic values were determined. In the experiments, 63.9% removal efficiency was achieved using 10 g/L adsorbent concentration for 10 mg/L Mn+2 under optimum conditions. As a result of the research, it was determined that the adsorption proceeds according to the pseudo-second-degree reaction and abides by the Langmuir isotherm. The thermodynamic constants of Delta H degrees= -4.866 kJ/mol and Delta S degrees= 21.44 J/mol were determined. As a result of this, the reaction was exothermic, spontaneous, and random, and adsorption was physical adsorption. As a result of the study, sewage sludge ash can be used in the treatment of water containing low concentrations of Mn2+ .
