The present study examines the ability of sago bark to remove Cu(II) ions in solution which was a solid waste from sago starch industry. The optimum condition utilizing batch experiment for Cu(II) sorption was achieved at pH 5, agitation speed 100 rpm, adsorbent mass 0.1 g, temperature 298 K, 800 mg/L of initial concentration in contact time 30 minutes with adsorption capacity 16.47 mg/L. Cu(II) removal showed a good agreement with Langmuir, Freundlich and Tempkin isotherm model. The kinetic data confirmed that Cu(II) sorption followed pseudo-secondorder model. The thermodynamic parameters revealed that the adsorption process was exothermic. Fixed bed column evaluation revealed that the best condition reached at 2 mL/min of flow rate with 9 cm bed depth. The breakthrough curve was suited to Thomas and Yoon-Nelson models. HNO 3 0.01 M gave better performance as a desorbing agent and adsorption capacity decreased after 3 adsorption-desorption cycles.
