摘要：The aim of this paper was to investigate adsorption of Mn (II) metal ions from aqueous solution by DOSS (Dioctyl sodium sulfosuccinate), SDBS (Sodium dodecylbenzenesulfonate) and SDS (Sodium dodecyl sulphate) an adsorbed chelating species on granular activated charcoal (GAC) which is prepared from Cordia Macleodii Tree Bark. The adsorbent dose, contact time, initial metal ions concentration, temperature, pH were determined and adsorption isotherms were obtained for Mn (II) metal ions. Kinetic data reveals that adsorption mechanism follows pseudo second order model also fitted to Freundlich and Langmuir adsorption isotherms. The surface modified GAC were characterised by SEM-EDAX and FTIR technology.
