摘　　要：以吡啶-2,6-二甲酸为原料,通过酯化和酰胺化反应制备得到多齿配体吡啶-2,6-二[N-(1’-甲基-2’-羟乙基)酰胺],并利用紫外-可见光谱分析方法研究了该配体对于重金属Cr^(3+)和Zn^(2+)离子识别性能。结果表明,该配体对于重金属Cr^(3+)和Zn^(2+)离子具有较高的选择性识别能力,并且不受其他金属离子的干扰。Pyridine-2,6- bis[[N-（1＇-methyl-2＇-hydroxyethyl）carbamyl] was synthesized by the esterification and amidation reaction with pyridine-2,6-diamides as the staring materials. The ion recognition of the ligand with Cr^3＋ and Zn^2＋ ion was investigated by the ultraviolet spectrophotometry. The results showed that ligand had good ion recognition for heavy metal Cr^3＋ and Zn^2＋ ion, and not affected by other metal ions.
