摘  要：氨基多羧酸（APCAs）具有优良的螯合性能，故可应用于去除污染水中金属。本文总结分析商业化和自备的吸附材料其官能化所常用四种APCAs：亚氨基二乙酸（IDA），次氮基三乙酸（NTA），乙二胺四乙酸（EDTA）和二乙酸（DTPA）。这些螯合吸附剂表现出其结构特征和独特的金属结合性能。以吸附动力学、等温吸附平衡模型和热力学模型作为基础对吸附现象的理论进行讨论。同时对APCA官能吸附剂最重要的应用进行描述。结果发现APCA官能吸附剂是去除污染水中金属的非常有前景的材料。

Abstract: Due to the excellent chelating properties of aminopolycarboxylic acid (APCAs), they can be used for the removal of metals from contaminated waters. This paper reviews the research results obtained for both commercial and self-prepared adsorbents functionalized with four most common APCAs: iminodiacetic acid (IDA), nitrilotriacetic acid (NTA), ethylenediaminetetraacetic acid (EDTA), and diethylenetriaminepentaacetic acid (DTPA). The structural characteristics and unique metal binding properties of these chelating adsorbents are presented. The theory of the adsorption phenomena is discussed based on the kinetics of adsorption, equilibrium adsorption isotherm models, and thermodynamic models. The most important applications of APCA-functionalized adsorbents are also described. APCA-functionalized adsorbents are found to be highly promising materials for metal removal from contaminated waters.
