英文摘要	Dried biomass of the Yellow Sea (China) macroalgae Sargassum thunbergii, Laminaria japonica (brown), Ulva pertusa, Enteromorpha linza (green) and Chondrus ocellatus (red) were studied in terms of their cadmium biosorption performance. Brown seaweed S. thunbergii revealed the highest removal efficiency at different initial Cd(II) concentrations. Equilibrium isotherms (Linear, Langmuir and Freundlich) and kinetics were obtained from batch adsorption experiments. Bio-sorption kinetics was found to be fast, with 90% of adsorption within 15 min. Fourier transform infra-red (FTIR) analysis of the seaweeds revealed the interaction of carboxyl, amino, sulphonate and hydroxyl groups on the seaweed surface with Cd2+ ions. The experimental results demonstrate that these seaweeds constitute a promising, efficient, cheap and biodegradable sorbent biomaterial for cadmium removal from wastewaters.
