Removal of Toxic Pollutants from Industrial Effluent: Sustainable Approach and Recent Advances in Metal Organic Framework

The water environment is mostly polluted by expanded industrial advancements and growth, which directly liberates various toxic pollutants into the water streams. These emerging pollutants cause several hazardous health issues to humans, animals, and the ecosystem. Conventional treatment methodology faces different issues in the recognition and removal of toxins, such as expense, facile operation conditions, and the prerequisite of high maintenance. To overcome this issue, adsorption is viewed as one of the most encouraging innovations for the removal of pollutants. Recently, metal-organic frameworks (MOFs) have been considered to be efficiently adsorbent, because of their porosity, high surface area, fine-tunable metal clusters, and easy functional surface engineering properties. This Review concerns the recent examinations on MOFs as proficient material in the removal of toxic contaminants from wastewater. The adsorption mechanism of toxic pollutants removal using MOFs-based materials was critically reviewed and discussed. At last, challenges and the viewpoint for future advancement of MOFs is summarized.
