The Research Progress on Photochemical Sensor for Heavy Metal Detection in the Environment
LEI Ping (Changsha Environmental Monitoring Center,Changsha 410013,China)
Abstract:Heavy metals,which can exist in the environment permanently,can cause serious damage to the ecological environment and to human health. It is important and urgent to establish an efficient,fast and sensitive method for detecting heavy metals. To overcome the shortage of traditional detection techniques which were established on the basis of large instruments,tedious detection process,and poor timeliness,photochemical sensors have been developed and widely used in various fields such as chemistry,environmental science,food and life sciences,due to their high selectivity,sensitivity,quick response,low cost,online and real-time. Herein the development of some commonly used photochemical sensors applied in heavy metal detection was reviewed.
Key words:heavy metal detection;photochemical sensor;environment;research progress
