Fe 3 O 4 nanoparticles can be used as an adsorbent for colour removal of printing ink which contribute as a pollutant in wastewater. Fe 3 O 4 was synthesized by coprecipitation method using FeCl 3 .6H 2 O and (NH 4 ) 2 Fe(SO 4 ) 2 .6H 2 O precursors dissolved in distilled water in mol ratio of Fe 3+ : Fe 2+ = 2:1. NaOH solution was added slowly into the iron solution with continuous stirring for 60 minutes in Argon gas atmosphere. After drying, Fe 3 O 4 nanoparticle product is obtained as black crystalline powder with an average particle size about 34 nm. The Fe 3 O 4 nanoparticles (0.1 g) were able to remove blue, red, and yellow colour with percentage of adsorption about 97%, 94%, and 62% for 40 minutes contact time and 100 rpm of stirring speed, respectively. Fe 3 O 4 nanoparticle can be separated from the printing ink solution by an external magnetic field.
