研究了八种不同的粉状活性炭 (PAC) 对微囊藻毒素-LR 的吸附情况，发现碳之间存在显着差异。木质碳显然是最有效的微囊藻毒素-1R 吸附剂，其次是煤基 PAC。椰子和泥炭藓基碳是最差的微囊藻毒素-LR 吸附剂。每种 PAC 的吸附程度与中孔体积（直径在 2.0 至 50 nm 之间）有关，而中孔体积取决于起始材料。然而，表面特性与起始材料无关。与墨累河水中天然有机物的竞争吸附显着降低了微囊藻毒素-1R 吸附的初始速率。微囊藻毒素-LR 吸附的最大水平也显着降低，其程度取决于碳的类型。
The adsorption of microcystin-LR by eight different powdered activated carbons (PACs) was investigated and found to vary markedly between carbons. Wood-based carbons were clearly the most effective microcystin-1R adsorbents followed by coal-based PACs. Coconut and peat moss-based carbons were the poorest microcystin-LR adsorbents.The extent of adsorption for each PAC was related to the volume of mesopores (diameters between 2.0 and 50 nm) which was dependent on the starting material. Surface characteristics, however, were not related to the starting material.Competitive adsorption with natural organics in River Murray water significantly reduced the initial rate of microcystin-1R adsorption. There was also a considerable reduction in the maximum level of microcystin-LR adsorption, the extent of which was dependent on the type of carbon.
