Abstract

Sargassum crassifolium is the origin strains of macroalgae from Indonesia which was the most
effectively adsorb heavy metals from liquid solution and it was investigated the adsorptive capability of heavy
metals in industrial wastewater. The macroalgae were collected at Kotok Besar Island, Seribu Island, North
Jakarta, Indonesia and were treated with the variety of pH 2, 3, 4, 5 and 9 for 60 minutes oscillation, in duplicate
assessment. The macroalgae were selectively effective for removal of Cd, Hg, and Pb compared with other
heavy metals, achieving 75-99.05% adsorption efficiency, mostly in acidic condition for 60 minutes oscillation,
except Hg. The selectivity order for other metal ion uptake by S. crassifolium was Cu>Fe>Co>Ni>Cr with
percentage removal below 56%. Due to the low cost, availability and significantly high adsorption capability, the
brown macroalgae S. crassifolium is able to be used for selective removal of heavy metals from industrial
wastewater effectively in acidic pH range.
