Freshwater cyanobacterial blooms are becoming increasingly problematic microbiological pollutants, especially for the water resource and surface natural lakes. Cyanobacterial blooms, which produce toxins and microcystins, negatively affect the quality of water, animal, and human health, and they have also negative impact on recreational activities. The effect of electrochemically prepared potassium ferrate (green oxidation agent) on the water polluted by cyanobacteria and cyanotoxins was studied. The two most frequently occurring cyanobacterial genus Microcystis and Anabaena and the most toxic and abundant microcystin MC-LR were successfully inactivated and treated by ferrate. Potassium ferrates were applied at different conditions, such as varied hydrodynamics flow of samples, pH, and Fe(VI) concentrations. High detected elimination efficiency was consequently tested on the real water matrix from microbiological polluted natural lake Šaštín-Gazárka in Slovakia. The ferrate application leads to the better chemical, biological, microbiological, and ecotoxicological outcomes.
淡水蓝藻水华正在成为日益严重的微生物污染问题,尤其是对水资源和地表天然湖泊而言。蓝藻水华会产生毒素和微囊藻毒素,从而降低水质,并对动物和人类健康产生负面影响,还会对娱乐活动产生负面影响。本研究探讨了电化学制备高铁酸钾(绿色氧化剂)对受蓝藻和蓝藻毒素污染的水的影响。最常出现的两种蓝藻属微囊藻属和鱼腥藻属以及最毒、最丰富的微囊藻毒素 MC-LR 都被高铁酸盐成功灭活和处理。在不同条件下应用高铁酸钾,如改变水样的水动力流、pH 值和六价铁浓度。随后在来自斯洛伐克微生物污染天然湖Šaštín-Gazárka 的实际水样中进行了高检测消除效率测试。高铁酸盐的应用带来了更好的化学、生物、微生物和生态毒理学结果。
