摘　　要：次氯酸根(ClO-)作为消毒剂和漂白剂的有效成分,常用于的人类生产和生活中.在狭小密闭空间内使用含有次氯酸根的消毒剂存在一定安全隐患,同时ClO-在体内的参与人体的多项生命活动,过量的ClO-存在于人体会对人体的免疫系统造成极大危害,诱发多种疾病.因此检测ClO-是十分必要的.采用一锅法,以聚乙烯亚胺为配体合成一种硫化镉量子点荧光探针实现对ClO-的检测,结果显示,探针对ClO-的识别具有较高的选择性和抗干扰能力,其检测范围在0~40 nmol/L,检测限为0.5 nmol/L.Hypochlorite(ClO-),as an effective component of disinfectant and bleach,is commonly used in human production and life.The use of disinfectant containing hypochlorite in a small confined space has certain safety risks.At the same time,ClO-participates in a number of life activities of human body in the body.Excessive ClO-in the body will cause great harm to the immune system of human body and induce a variety of diseases.Therefore,it is necessary to detect ClO-.In this paper,a cadmium sulfide quantum dot fluorescent probe was synthesized by one-pot method using polyethylenimine as the ligand to detect ClO-.The results show that the probe has high selectivity and anti-interference ability in ClO-recognition,and the detection range is 0~40 nmol/L,and the detection limit is 0.5 nmol/L.
