We used macroalgae (Hizikia fusiformis, Laminaria, and Undaria pinnatitida) to adsorb heavy metal ions. For pH from 2 to 8 adsorption of chromium reached a maximum at pH 4, and then decreased at higher pH as determined by Atomic Absorption Spectrometer. At the same conditions adsorption of copper was kept increasing up to pH 8. This behavior was different from lead, cadmium, and manganese, for which adsorption increased up to pH 4, and then did not change significantly at higher pH up to 8. We compared adsorption of heavy metal ions in solutions containing single metal ion and five metal ions (lead, cadmium, manganese, chromium, and copper). In the case of chromium the presence of other metal ions improved the adsorption of chromium ion. However, presence of other metal ions decreased the adsorption of copper ion suggesting that we may be able to enhance the adsorption by adding or eliminating other ions in the solutions.
