主要以Schiff碱的水溶性配合物的合成,催化氧化动力学为研究目的。先以水杨醛等为原料,合成出Schiff碱的Co,Ni,Cu的配合物,通过FTIR和UV-VIS检测配体是否与金属离子配位。再分别研究这些配合物对邻苯二酚氧化的影响。通过紫外可见分光仪,预先对邻苯二酚,Cu配合物,Co配合物,Ni配合物在200~800纳米进行扫描,找出特定吸收峰,再用定点扫描的方法,在特定吸收波长处找出时间与邻苯二酚吸收值的关系,从而对邻苯二酚的氧化进行监测。
The main synthesis of Schiff base water-soluble complexes, catalytic oxidation kinetics for the study. First, salicylaldehyde and other raw materials, synthesis of Schiff base Co, Ni, Cu complexes, FTIR and UV-VIS detection of ligand coordination with metal ions. The effects of these complexes on catechol oxidation were studied separately. By UV-Vis spectrometer, the catechol, Cu complex, Co complex, Ni complex were scanned at 200-800 nm in advance to find the specific absorption peak, and then fixed-point scanning method was used to detect the specific absorption wavelength Find out the relationship between the time and catechol absorption, and thus catechol oxidation was monitored.
