Research progress in the removal of microcystins from water by activated carbon

对国内外活性炭去除水体中微囊藻毒素的研究进展进行了综述。详细阐述了活性炭对微囊藻毒素的吸附去除机理及水体中天然有机物、pH、氯等外界因素对活性炭吸附性能的影响,认为物理扩散、静电引力和降解作用是活性炭吸附去除藻毒素的主要机理。通过改性和生物再生能够有效提高活性炭对微囊藻毒素的去除率并延长其运行周期。

The research progress in the removal of microcystins（MCs） from water by using activated carbon in China and abroad is summarized.The effects of activated carbon on the removal mechanism of the microcystins adsorption and the effects of exterior factors,such as natural organisms in water,pH,chlorine,etc.on the adsorption capacity of activated carbon are expounded in detail.It can be concluded that physical diffusion and static attractive force are the main mechanisms of the removal of microsystins by activated carbon adsorption.It can be confirmed that modification and bio-regeneration could improve the microcystins removal efficiency by using activated carbon and prolong its operating period effectively.
