摘　　要：羟基药剂具有氧化力极强、杀灭微生物的生化反应速度极快的特性。在容积1.8m3的水槽里进行了羟基对微藻的光合色素影响的中宇宙规模实验。羟基质量浓度达到0.55mg/L时,微生物的叶绿素a、b含量均低于检测方法的最低限值,其衰减率为100%,类胡萝卜素衰减率为92.3%,脱镁叶绿素增加了15.05倍。实验数据表明,羟基药剂将是治理赤潮的绿色有效方法。Hydroxyl radical has the characteristic of strong oxidation and a fast biochemical reaction rate of killing microorganisms. A pilot-scale experiment was carried out in a 1.8m^3 water tanker to examine the effects of hydroxyl radical on the content of photopigments contained by microorganism＇s cells. As the ratio concentration of hydroxyl radical reached 0.55mg/L, the contents of chlorophyll a and chlorophyll b were both lower than the detection limit, with an attenuation rate of 100%; that of carotenoid decreased by 92.3%; while the content of phaeophytin increased by 15.05 times. These experimental data indicate that using hydroxyl radical will be a green and effective method to treat red tide.
