报道一种利用不同浓度的苯酚对大环二价铜配合物催化的B-Z化学振荡体系的扰动来检测苯酚的方法.大环铜配合物[CuL](ClO4)2是一种类似卟啉环的化合物,其中L为5,7,7,12,14,14-六甲基-1,4,8,11-四氮杂十四-4,11-二烯.实验表明苯酚可以造成大环二价铜配合物催化的B-Z振荡体系的振幅急剧增大.苯酚浓度的对数在2.0×10-7～2.5×10-3M的范围内与振幅的增加值呈正比例的关系,其相关系数为0.994 5.讨论了苯酚对体系扰动的可能机制.
A method for detecting phenol by using different concentration of phenol to perturb BZ chemical oscillation system catalyzed by macrocyclic bivalent copper complex is reported. The macrocyclic copper complex [CuL] (ClO4) 2 is a porphyrin ring Wherein L is 5,7,7,12,14,14-hexamethyl-1,4,8,11-tetraazatetra-4,11-diene. Experiments show that phenol can cause macrocyclic bis The amplitude of the BZ oscillating system catalyzed by copper complex increased sharply.The logarithm of phenol concentration was directly proportional to the increase of amplitude in the range of 2.0 × 10-7 ~ 2.5 × 10-3M with a correlation coefficient of 0.994 We discuss the possible mechanism of phenol perturbation to the system.
