Biosorption using macroalgae is the efficient method used to eliminate heavy metals from liquid waste. Eucheuma spinosum, Padina minor and Sargassum crassifolium are the origin species of macroalgae from Indonesia that were used to analyze the ability of adsorption of lead from aqueous solution.  Samples collected at Pari and Pramuka Island, Seribu Island, North Jakarta, Indonesia were used to adsorb lead with variety of adsorption time of 10, 20, 30, 45, 60, 90 and 120 minutes and variety of initial concentration of lead, 200, 300, 400,500, 750 and 1000 mg/L, using duplicate assessment at the pH 5. The highest lead removal was 98-99% in the concentration of 750 mg/L for E. spinosum and of 1000 mg/L for P. minor and S. crassifolium which was achieved within 60 minutes. The binding of lead by S. crassifolium followed Freundlich model while Langmuir model fitted better in E. spinosum and P. minor with their R&lt;sup&gt;2&lt;/sup&gt; of 0.976, 0.984 and 0.934, respectively. The maximum adsorption capacity of lead was 55.56 mg/g for S. crassifolium, followed by P. minor and E. spinosum was 40.00 and 32.26 mg/g.&lt;strong style=&quot;font-style: italic;&quot;&gt; &lt;/strong&gt;&lt;/p&gt; &lt;p&gt;&lt;strong&gt; &lt;/strong&gt;&lt;/p&gt;}, number={2}, journal={Asian Journal of Applied Sciences}, author={Putri, Lily Surayya Eka}, year={2016}, month={Apr.} }
