通过分析电解前后铜绿微囊藻液的光密度与叶绿素荧光动力学参数变化，探究了氯离子（Cl－）浓度及电流密度对微电流电解抑制铜绿微囊藻生长的影响。结果表明：微电流电解产生的活性氯在抑藻过程中起了重要作用，对初始细胞密度5×105个／mL、体积100 mL的铜绿微囊藻液而言，当藻液中初始Cl－浓度为18 mg／L时，电解后藻细胞的生长受到了完全抑制；而对于无氯藻液，电解后藻细胞的生长未受明显影响。当电流密度为10 mA／cm2、电解时间为15 min，而藻液中的初始Cl－浓度在0～18 mg／L范围内时，电解抑藻效率会随着Cl－浓度的升高而逐步提高；并且当Cl－浓度≥12 mg／L时，电解后藻细胞彻底死亡，无法再恢复活性。当电解时间为15 min、藻液中初始Cl－浓度为18 mg／L，电流密度在0～20 mA／cm2范围内时，随着电流密度的增加电解抑藻效率也会提高。成果为深入研究微电流电解的持续抑藻机理提供了基础。

Effects of chlorine ion (Cl-)concentration and current density on Microcystis aeruginosa’s growth inhib-ited by low-amperage electric current were investigated.The results showed that active chlorine played an important part in algae growth inhibition.When the algal solution was electrolyzed under the same condition,the growth of al-gae cells could not be sustainably inhibited unless sufficient amount of active chlorine could be generated in the e-lectrolyte.The efficiency of electrolytic inhibition on algae increased with the increase of Cl-concentration when Cl-concentration was changed in the range of 0-18 mg/L,current density was 10 mA/cm2 and electrolysis time was 15 min.When Cl-concentration was not less than 12 mg/L,the growth of algae cells would be sustainably in-hibited .The efficiency of electrolytic inhibition on algae would also be increased with the increase of current density when current density was changed in the range of 0-20 mA/cm2,Cl-concentration was 18 mg/L and electrolysis time was 15 min.
