Abstract

Algal biomass was used in our study in order to remove some metals. After packing of 40~60 mesh algae powder into column for use of metal adsorbent, the metal solution of 1mL/min of flow rate was eluted to adsorb in algae. More amount of Cu(II) or Zn(II) ion in green algae, Ulva pertusa Kjellman than in brown algae, Sargassum horneri (Turner) C. Agarch were adsorbed and Cu(II) ion was more adsorbed in both algae than Zn(II) ion. Recovery of metal from algae is showing higher in acidic or neutral than in alkalic conditions. Cu(II) ion is recovered relatively higher than Zn(II) ion in our system.
