Metal-Organic-Frames (MOFs) Based Electrochemical Sensors for Sensing Heavy Metal Contaminated Liquid Effluents: A Review

Abstract

Toxic heavy metal ions may have adverse health effects on human health. sensing and effective removal is an important issue. Metal-organic frameworks (MOFs) are a novel group of crystalline porous materials. Because of their extremely high surface areas, optimized pore volumes and pore size distributions for specific detection, electrochemical sensors based on MOF's are gaining popularity. They are reliable, easy to use and have good sensitivity. This review will give an insight into the selection of MOF's as heavy metal sensing devices and the mechanism behind the detection of specific metal ions shall also be explained. Challenges and prospects for practical applications of MOFs in heavy metal ion detection will be also discussed.
