Maximum removal capacity of the copper(II) ion from aqueous solutions was achieved at pH 5 0 Adsorption data was well fitted to the Langmuir and Freundlich isotherms. Langmuir monolayer capacity was a value of 15.05 mg/g The results in this study indicate that the activated carbon obtained from pine cone can be an effective adsorbent for removal of copper(II) ions from aqueous solutioneninfo:eu-repo/semantics/closedAccessAdsorptionAdsorption IsothermActivated CarbonPine ConeRemovalCu(II)Heavy-MetalsCopper(Ii) IonsAdsorptionSorptionBiosorptionIsothermsCadmiumWaterEquilibriumAdsorbentsArticle22539363942Q4WOS:000279844500083
