摘要
水体中的重金属在环境中具有持久性、毒性和累积性特点,因此对其污染修复一直是环境污染治理领域关注的焦点。传统的重金属去除方法成本较高,同时会产生大量有毒有害的化学污泥。农业废弃物是一种天然、廉价、可再生、可替代的高性能吸附材料,在吸附去除水体重金属方面得到了实际应用,其吸附动力学模型及吸附机理也得到了初步的探究。结合目前国内外研究成果,着重介绍了近年来利用农业废弃物处理水体重金属污染的研究进展,并提出今后的研究方向。
Heavy metals in water have attracted a considerable attention in the field of environmental pollution control due to their persistence, toxicity and accumulation. Conventional treatment methods have the problems of high cost and toxic chemical sludge produced. Agricultural waste material is a kind of natural, low cost, renewable, replaceable and high-efficiency adsorbent, which is practically applied in the treatment of heavy metals in water. The adsorption kinetic model and adsorption mechanism have been preliminarily explored. According to the current research achievements at home and abroad, the advances in research on agricultural waste material for the treatment of heavy metal ions in water were reviewed, and the research directions in the future were proposed.
