摘要
以2,2-联氮-二(3-乙基-苯并噻唑-6-磺酸)二铵盐(ABTS)为介体,研究了漆酶/ABTS介体系统对蒽与苯酚共存体系的降解效果,并考察了不同苯酚浓度对共存体系中蒽降解效果的影响。同时,分析了漆酶/ABTS介体系统对共存体系的作用机理。结果表明,苯酚的引入会抑制蒽的去除,且随着苯酚浓度的增大,蒽降解被抑制地更明显,而蒽对苯酚的降解影响可以忽略不计;蒽体系和蒽与苯酚共存体系中蒽的氧化降解过程均符合一级动力学规律。
2 ,2 - azino - bis - （3 - ethylbenzthiazoline -6 - sulfonic acid） （ABTS） is selected as a mediator to study the degradation of coexistence system of Anthracene and phenol by laccase/ABTS mediator system and the effects of phenol con-centration on the degradation of anthracene are investigated .Besides ,the degrading mechanism of coexistence system is ana-lyzed .The results show that the introduction of phenol can inhibit the removal of anthracene and with the increase of the concentration of phenol ,anthracene degradation is suppressed more obviously ,while the effect of anthracene on phenol degradation is negligible .The process of anthracene oxidative degradation in anthranece system and coexistence system ap-proximately accords with the first - order reaction .
