【摘要】 本文以大孔聚氯乙烯树脂为原料,合成聚乙烯乙二胺丙酰胺肟螯合树脂,建立了利用该螯合树脂富集分离20余种微量元素的ICP化学光谱法,讨论了其富集各待测元素的性能和机理,进行了螯合树脂的红外光谱等结构分析及样品中微量元素的富集和测定,结果较满意。更多还原

【Abstract】 Poly(vinyl-ethylenediamine-propaneamideqxime) chelate resin was synthesized’ by using macroporous polyvinyl chloride as an original material.The ICP clcmical spectrum method was established for enriching and separating’ 20 kinds of trace elements with, the chelate resin. Its performance and mechanism for enriching some trace elements are discussed.The structural analysis of chelate resin was performed by SEM and infrared spectrum et al. The trace elements in samples were enriched and determined with satisfactory results.更多还原
