摘　　要： 本文研究了银离子去除赤潮藻的效果,实验结果表明,当银离子浓度在0.125～0.25mg/L时,能有效抑制和灭杀赤潮生物,但有效期短,为此研制了含银玻璃除藻剂,当这种药剂投加到水体后,随玻璃逐渐溶解缓释出银离子而灭杀赤潮藻,延长了有效期;此外,本文还研究了含银玻璃除藻剂在灭杀赤潮藻后银离子的残留浓度以及对环境的影响。 This paper studied the removal efficiency of the red tide algae by silver ions. The results showed that silver ions can control developing of the red tide algae effectively in the range of concentrations： 0.125 to 0.25 mg/L. But the time of control is short. For this reason ,we made a glass algicide containing silver ions. The silver ions are gradually elluted from the algicide as it dissolve when it is put into water. The silver ions can kill red tide algae and the time of control is prolonged. Morever, The paper studied the surplus silver ions concentration after the glass algicide acted with red tides and the influence of the silver ions to the environment.
