研究了新配体TTBA与二价锌离子生成配合物的光度特征。在较宽的pH范围内．新试剂和锌离子形成1：1的谈黄色配合物.稳定常数K＝5．36×105’，λmax=310urn表观摩尔吸光系数ε=2.35×105l／moL·cm，并且在3．8×10-8～1×10-5mol／L范围内具有良好的线性关系。
The photometric characteristics of the complexes formed by the new ligand TTBA and divalent zinc ions were studied. Within a wide pH range. The new reagent formed a 1: 1 yellow complex with zinc ions with a constant K = 5.36 × 105 ’and λmax = 310urn. The apparent molar absorptivity ε = 2.35 × 10 5 l / moL · cm, 10-8 ~ 1 × 10-5mol / L range has a good linear relationship.
