摘要
由于藻类高的重金属富集能力、环境友好、修复效率高等特点,藻类被认为是理想的生物修复材料,并成为环境领域的研究热点。结合国内外藻类去除水体重金属的研究进展,介绍了各藻类生物吸附剂的分类,阐述藻类吸附和富集重金属机理,以及影响重金属吸附的主要因素(吸附时间、活体藻与非活体藻、微藻粒径、溶解性有机质),并对藻类富集重金属在水体修复应用的趋势进行分析。
Algae are considered as ideal bioremediation materials because of their high enrichment ability, environmental friendliness and high repair efficiency, therefore become a hot spot in the environmental research. The article reviewed the research progress of algae removal of heavy metals in the water, introduced the classification of the alga biological adsorbent, focused on adsorption and enrichment mechanism of heavy metal on algae, and main factors affecting the adsorption of heavy metals （adsorption time, living algae and not living algae, algae size, dissolved organic matter）, and the accumulation of heavy metals in the application of algae water restoration trend analysis.
