Abstract: The continuous population growth and technological development are contributing factors to the increased contamination of effluents with toxic metals. The removal of such metals from effluents has become an important subject for scientific research. Among the most used methods, adsorption has shown good potential to treat such effluents. In this work we investigated the metals affinity with the residue of alginate extraction from the seaweed Sargassum filipendula. The alginate residue has shown good results in the removal of metal contaminated industrial effluent and is an interesting subject of research. The experimental tests were performed using different metal solutions with concentration of 1.0 mmol.L-1, at 180 rpm in room temperature 25 °C for a period of 24 h under controlled pH 3.5. The alginate residue can be used as a bioadsorbent in the treatment of metals contaminated effluents with good results. The first and second extractions residue has shown similar ability of ion removal
