摘要:

腐殖酸对环境中各类污染物的生物活性和迁移转化具有积极影响,铁氧化物具有较高的比表面积、较强的氧化还原以及配位络合能力,优良的理化性质使得腐殖酸和铁氧化物均能较好地去除重金属离子。综述了腐殖酸、铁氧化物以及腐殖酸-铁氧化物复合材料对重金属的去除机理,腐殖酸、铁氧化物二者的交互作用。对腐殖酸-铁氧化物复合材料目前存在的不足提出了建议,并对今后在水体重金属污染治理中的应用进行了展望。

Abstract:

Humic acid has profound effects on the biological activity and migration and transformation of inorganic and organic pollutants in the environment. Iron oxide has a high specific surface area, strong redox and coordination complexing ability. The excellent physicochemical properties enable both humic acid and iron oxide to remove heavy metals from water. In this paper, the mechanism of heavy metal removal by humic acid, iron oxide and humic acidiron oxide, and the interaction between humic acid and iron oxide are reviewed. Suggestions for the current deficiencies of humic acid-iron oxide composites are given. The future application in the treatment of heavy metal pollution in industrial wastewater is prospected.

Key words: humic acid, iron oxide, heavy metal, industrial wastewater
