Exploration of Metal Organic Framework (MOF) as Adsorbent in Treatment of Wastewater

Abstract

Organic dyes and heavy metals are renowned environmental contaminants due to their hazardous, long life time in the environment, and capability to accumulate into the human body. Most heavy metals are accumulated naturally, however only some are derived from anthropogenic sources. In the recent decades, metal organic framework (MOF) and their most fashionable derivatives are extensively examined to eradicate heavy metals and organic dye substances from polluted water as powerful adsorbent materials. MOFs have forever exposed attractive applications in adsorption technologies and membrane separation, among which water-stable MOFs are predominantly important in wastewater treatment (WWT) relevance. MOFs like metal-organic polymers, hybrid organic–inorganic materials, organic zeolite materials and coordination polymers have increased awareness and many of the MOFs have been synthesized to eradicate heavy metals and organic dyes from waste water, because of their outstanding characteristics like large surface area, stability, greater porosity which make the MOF a strong and powerful adsorbent. In this paper, we discussed about the removal of hazardous heavy metals and organic dyes using MOF materials and their analogues as strong adsorbents for contaminated waste water.
