中文摘要：
在pH6.0,200 mmol/L磷酸盐缓冲溶液中使用紫外差光谱、荧光光谱研究了Cu（Ⅱ）与N,N‘-乙烯-二[2-（2-羟基苯基）苷氨酸]（EHPG）的结合.结果表明Cu（Ⅱ）可与EHPG形成1∶1的稳定配合物,其在265 nm处的摩尔吸光度为（5.462±0.035）×10^4cm^-1.mol^-1.L.配合物条件结合常数为：logKCu-EHPG=15.62±0.18.
英文摘要：
In 200 mmol/L phosphate buffer with pH6.0,the reaction of N,N’-ethylenebis [2-（o-hydroxyphenolic）glycine] with cupric ion was monitored by UV difference and fluorescence spectra.The molar absorptivity of Cu（Ⅱ）-EHPG at 265 nm is（5.462 ± 0.035）×10^4 cm^-1·mol^-1·L.The conditional binding constant is logKCu-EHPG=15.62±0.18.
