Continuous biosorption process for removal of lead an copper by laboratory scale fixed-bed reactor was carried out using Ca-loaded Laminaria japonica. All biosorption processes were observed as cation exchange such as Pb2+ vs. Ca2+, Cu2+ vs. Ca2+ and Pb2+ vs. Cu2+. The affinity of lead ions towards L. Japonica was stronger than that of copper ions because the initial amount of desorbed Cu2+ in Cu-Pd system was higher than that of eluted Pb2+ in Pb-Cu system.
