英文摘要	Radionuclides accidentally released from nuclear power plants, such as Cs-137 and Co-60, can lead to severe contamination of marine ecosystems. Living macroalgae are efficient in absorbing metal elements from seawater. A 10-day simulation was conducted to assess the potential of scavenging cesium (Cs) and cobalt (Co) with live Ulva prolifera that was cultured in seawater medium containing Cs and Co in different concentrations (0 (the control), 10, 20, 50, and 100 mg/L). In the experiment, 5 kg (fresh weight) of U. prolifera was cultured in natural seawater in 90-L tanks. Results showed that after the experiment, the average bioconcentration factors (BCFs) of the control group were 247.2 and 1 126.4 for Cs and Co, respectively. The absolute absorption quantity of U. prolifera increased and the BCFs decreased with the increase in Cs and Co concentrations. The biosorption of the two metals on the first day well fit the pseudo-second-order equation (R-2>0.95), indicating that adsorption is the rate-limiting step in the total biosorption process. Concentrations of both metal ions declined significantly in the first hour and decreased by 25.2% and 15.5% in 48 h, respectively. Therefore, live U. prolifera is efficient at scavenging Cs and Co in seawater, providing potential applications for the phytoremediation of radionuclides contaminated seawaters.
