实验室实验比较了甲藻链状裸甲藻的细胞和毒素的去除效率，使用三种浓度的细胞和三种浓度的红粘土、蒙脱石、斜发沸石、氧化钙、氢氧化钙、硫酸铝、壳聚糖、活性二氧化硅和聚合氯化铝作为混凝剂或絮凝剂。使用最小浓度标准来选择壳聚糖、氧化钙和氢氧化钙以达到去除细胞的最大效率。将它们成对组合以测量它们的联合性能。在所有情况下，细胞去除效率均为 95-99%。氧化钙+壳聚糖的组合有效去除了细胞，但未能去除链状G. catenatum产生的细胞外毒素。 (C) 2015 Elsevier B.V. 保留所有权利。
Laboratory experiments compared the removal efficiency of cells and toxins of the dinoflagellate Gymnodinium catenatum, using three concentrations of cells and three concentrations of red clay, montmorillonite, clinoptilolite, calcium oxide, calcium hydroxide, aluminium sulfate, chitosan, activated silica, and polyaluminium chloride, as coagulating or flocculating agents. Chitosan, calcium oxide, and calcium hydroxide were selected using the criterion of minimum concentration for maximum efficiency for removing cells. These were combined in pairs to measure their joint performance. In all cases, removal efficiency of cells was 95-99%. A combination of calcium oxide + chitosan effectively removed the cells, but failed to remove extracellular toxins produced by G. catenatum. (C) 2015 Elsevier B.V. All rights reserved.
