Biotechnology Letters Aims and scope Submit manuscript

Summary

We reportUndaria pinnatifida as a potential biosorbent for lead removal.U. pinnatifida exhibited approximately 350 mg of lead uptake capacity per gram of dry biomass within a pII range of 3 to 4. The major cellular component ofU. pinnatifida in lead binding was thought as alginic acid existing in the cell wall.U. pinnatifida adsorbed lead ion selectively over other alkaline metal ions such as K+, Na+, Mg++ and Ca++. It was confirmed by using instrumental analysis including EDX and XPS thatU. pinnatifida adsorbed lead ions on the surface of itself.
