摘　　要： 模拟研究了海带、洋栖菜、甲壳素、壳聚糖等生物载体吸附水溶液中铜离子后对赤潮生物的杀灭和控制作用.生物载体投放到水体后,载体缓慢释放出铜离子而杀灭赤潮藻,延长了有效期,增强了杀藻能力.研究结果表明,海带不仅适用于生物吸附去除废水中重金属铜,同时其作为载体适用于吸附Cu2+后杀灭赤潮藻. ：In this paper, the capacities of some biomass carriers for copper ion were studied. Preliminary research was carried out on the desorption capacities of copper ion from the biomass carrier and the removal efficiency of the red tide organisms by it. The copper ions are gradually elluted from the biomass carrier which has adsorbed copper when it is put into water. The copper ions could kill and control the red tide organisms. The time of control is prolonged. The capability to remove algae has strengthened and the cost has been lower. The results indicated that the biomass of the Laminaria japonica is not only suitable for the development of efficient biosorbents for the removal of heavy metals(copper) from waste water, but also for the control of the red tide.
