摘要
重金属污染已成为全球性的环境问题,脱除重金属是治理重金属污染的主要途径。海藻酸钠(SA)本身无毒、性质稳定、价格低廉,具有较强的胶凝性、成膜性和络合能力,既可作为脱除重金属的吸附材料,又可作为脱除重金属的固定化载体,在重金属脱除中具有广泛的应用。本文重点综述了SA凝胶球、SA复合膜、SA纳米复合材料、SA分子印迹聚合物脱除重金属,以及SA作为单一固定化载体和复合固定化载体脱除重金属的研究进展。展望了SA脱除重金属的应用前景。
Heavy metal pollution has become one of the most serious environmental problems today,and removal of heavy metals is the main approach to control heavy metal pollution.Sodium alginate（SA） has many advantages,such as non-toxic,stable nature,low cost,strong gelation ability,film forming ability and complexation ability.It has been widely used as an adsorption material or an immobilized carrier in the removal of heavy metals.This paper focuses on the application of SA gel bead,SA composite film,SA nano composite material,SA molecular imprinted polymer and SA immobilized carrier for the removal of heavy metals.And the development prospects of SA for the removal of heavy metals are also presented.
