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。
The synthesis of N-1,1’- (2,2’-dicarboxy-4,4’-biphenylene) -bis- (3-N-hydroxy-3-N-phenyltriazene) (NDDTNHPUN) Synthesis method, structure demonstration, analytical performance and its application in photometric analysis. NDDTNHPUN has a high color rendering sensitivity to molybdenum and good recognition. In photometric analysis, ε467.5 reached 2.35 × 106L · mol-1 · cm-1. Used for spectrophotometric determination of trace molybdenum, the results consistent with atomic absorption spectrometry.
