摘要
合成了大孔水杨酰腙 -聚苯乙烯型螯合树脂 ,通过静态吸附和动态吸附方法 ,研究了树脂对常见过渡金属离子的螯合性能。结果表明 ,在 p H=5 .5时 ,树脂对 Zn2 +的吸附量达 0 .81 mm ol· g- 1树脂。据此提出了一个通过分离富集 ,来测定牛奶中微量锌的新方法。
A macro-porous chelating resin of polystyrene-salicyacylhdrazone was synthesized and its absorbability for common translated metal ion was studied. It was found that the resin had a good absorption ability for Zn^(2+) at pH=5.5 .The absorption capacity was 0.81mmoL/g. Based on this, a new method was given to detect trace zinc in the milk powder by separation and enrichment. The new chelating resin had been used to separate metal ion in wastewater of chemical laboratory.
