摘要/Abstract

摘要： 本文在空气-乙炔焰中探讨了络合剂的类型,络合剂分子中键合原子的种类、数目及其相对位置,有无共轭体系及其大小,在成络过程中能否形成螯合环,以及有无磺酸基等络合剂的结构因素对镱增感效应的规律和机理。

Abstract: The influence of the structural factors (the type of complcxing agents, the kind and the number of bonding atoms and their relative position, the conjugated system and its size, the formation of chelate ring and the molecule with or without sulfonic acid group) of organic complexing agents on the enhancement effect of ytterbium was studied in an air-acetylene flame. The rule and the mechanism of the enhancement effect were discussed. The results indicate that the kind of bonding atom is a important factor deciding enhancement OT suppression action of complex-ing agent and the information obtained should be a comprehensive result affected by all these factors cooperatively in this case.
