技术领域
本发明涉及传感器技术领域,特别是涉及一种用于二噁英检测的传感器及其制备方法。
背景技术
持久性有机污染物(POPs)是一类具有环境持久性、生物累积性、长距离迁移能力和高生物毒性的特殊污染物。二噁英是持久性有机污染物中的一种,也是最具代表性的有毒化学污染物。二噁英是一类化合物的总称,按化学结构可分为两大类:一类为多氯代二苯并二噁英(PCDDs),一类为多氯代二苯并呋喃(PCDFs),总共有210种同类物,在二噁英化合物中研究最多最典型也是毒性最强的物质为2,3,7,8-四氯代二苯并二噁英(2,3,7,8-TCDD)。
二噁英广泛存在于环境介质中,主要是在废弃物的燃烧,化学工业生产,工业制造以及热处理工艺过程中产生的。90%来源与含有氯化合物垃圾焚烧过程。如多氯联苯,五氯酚,聚氯乙烯等的燃烧。随着垃圾燃烧炉的增加二噁英的污染也将越来越严重。二噁英主要以两种形态存在,即挥发性的二噁英气体和固态的二噁英颗粒。常温常压下二噁英为白色固体晶体,有着较高的熔沸点,蒸汽压很小,不溶于水和有机溶剂,但脂溶性很强,并且易吸附在土壤,沉积物和空气飞尘上。目前为止,根据对二噁英检测原理的不同,可将二噁英的检测方法主要分为化学分析法、免疫检测法和生物法三种,目前现有的二噁英检测方法大多采用化学分析法,其存在检测设备体积庞大,且前处理复杂,检测不方便等技术问题。因此,亟需一种二噁英检测传感器来解决上述技术问题。
