Abstract
The functional group on marine algae (Sargassum crasifolium) has been modified using NaOH, formaldehyde and citric acid as a modifier. The modified of algae is used for the Pb(II) uptake. The experimental results showed that the modification of functional group on algae Sargassum crasifolium using NaOH much better than formaldehyde and citric acid, with the sorption capacity 1.25 mg Pb/g algae followed by 0.83 and 0.69 mg Pb/g algae powder for formaldehyde and citric acid modification, respectively.
