摘要
阐述了N－1，1＇－（2，2＇-二羧基-4，4＇-联苯撑）-双-（3－N-羟基-3-N-苯基三氮烯）（NDDTNHPUN）的合成方法、结构论证、分析性能及在光度分析中的应用。NDDTNHPUN对钼有很高的显色灵敏度和很好的识别能力。在光度分析中，ε467.5达2．35×106L·mol-1·cm-1。用于光度法测定痕量钼，结果与原子吸收光谱法一致。
This article is on the research on synthetic ways,structural proof,analytica1 behavior and application in phototnetric analysis of N-1 ,1'-(2, 2' -dicarboxyl-4,4' -diphenyl )-bis- (3-N-hydroxy-3-N-phenyl-tri-azene ). It is highly chromogenic, sensitive and has good selectivity for Mo. In photometric analysis, E675 value is 2. 35 ×106L. mol-1· cm-1. The method was used to determine trace Mo and gave the same result as AAS.
