呋喃衍生物糠醛与二乙烯三胺反应制得了含有Schiff碱基、胺基及大共轭π键的氮配位螯合树脂 ,应用电感耦合等离子体发射光谱研究了所得螯合树脂对贵金属元素Au、Pd、Pt、Rh、Ru、Ir及重金属元素Hg的吸附性能。结果表明 ,所得螯合树脂在较宽的酸度范围内能很好地吸附Au、Pd、Pt、Rh、Ru元素 ,具有优良的吸附选择性及较高的富集倍数 ,特别是对Au能达到定量吸附与洗脱。同时 ,在一定酸度条件下亦对Pt、Ir及Hg显示良好的吸附性能
Furan derivatives of furfural and diethylenetriamine reaction Schiff bases, amine groups and conjugated π bond nitrogen chelating resin, the use of inductively coupled plasma emission spectroscopy of the resulting chelating resin on the precious metal elements Au , Pd, Pt, Rh, Ru, Ir and heavy metal elements Hg. The results show that the obtained chelating resin can adsorb Au, Pd, Pt, Rh and Ru well within a wide range of acidity, has excellent adsorption selectivity and high enrichment factor, especially for Au Quantitative adsorption and elution. At the same time, Pt, Ir and Hg also showed good adsorption performance under a certain acidity
