Design, Syntheses and Functional Studies of Porous Materials for Remediation of Environmental Pollutants

Abstract

Environmental pollution has become a pressing and paramount concern worldwide, because of its huge threat to the living systems. Among different type of environmental pollution, water pollution is accounting as one of the major issue now a days. Chemical water pollution by different toxic and hazardous wastes like dye molecules, metal ions, oxo-anions, radioactive wastes, pharmaceutical wastes etc. has earned huge concern globally. In this regard, we sought to demonstrate detection and sequestration of water pollutants with porous materials (such as metal-organic frameworks and porous organic materials) from water. Functionalized porous materials have been strategically designed for the removal of the targeted analytes. In brief, stable functionalized MOF have been employed for the selective detection of toxic Hg(II)-ion. Further, post-synthetically modified porous organic compound has been utilized for capture of cationic dyes from water. Sequestration of radioactive iodine from water has been demonstrated with hydroxy functionalized porous materials (with the help of non-radioactive isotope). In addition, efficient removal toxic and hazardous oxo-anions have been shown with an ionic porous network via anion exchange as a tool.
