摘　　要：用水杨醛与牛磺酸以1∶1的比例在无水乙醇中反应,合成了水杨醛缩牛磺酸席夫碱。再与Cu(Ⅱ)金属离子络合,合成了Sch iff碱铜配合物,红外光谱证实了其结构。研究了不同条件下该配合物对H2O2分解的催化性能。结果表明,该配合物能迅速催化过氧化氢的分解,在20℃、pH=11、0.05 g配合物的条件下,5%过氧化氢在20 s内分解放出32 mL氧气。催化反应速度还与配合物用量、过氧化氢浓度和溶液pH值等因素有关。Taurine-salicylic Schiff base was successfully synthesized from salicylaldehyde and taurine （1：1 ）in the solution of alcohol, then its Cu complex was made from the Schiff base and Cu（ Ⅱ ）, structure of the complex was verified by IR. Catalytic activity of the complex for decomposition of H2O2 solution was determined at different conditions. The research result expressed that this Cu complex could quickly catalyze the decomposition of H2O2, 5% H2O2 released 32 mL 02 within 20 s catalyzed by 0.05 g complex at 20℃ and pH = 11. Speed of the decomposition was influenced by use level of the complex, concentration and pH of H2O2 solution.
