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.
