A Novel Strategy for Remediation of Heavy Metal Removal and Oil/Water Separation from Carbon-Based Nanohybrid

Abstract

Increasing the world population results in the consequent consumption of primary resources, which produces high amounts of waste. The increasing amount of waste has negatively impacted the environment and ecosystem. The growing population demands a high amount of food resources, which increases anthropogenic activities. So, Environmental pollution has become a severe problem due to this anthropogenic activity affecting our planet. This problem cannot be neglected and has become the most challenging task of the 21^st century. Researchers are putting effort into developing new nanohybrid, which should be environmentally friendly, with greener methods of synthesis to overcome and remediate the environment from pollutants. Scientists are trying to move towards nanotechnologies and nanomaterials to resolve the upcoming challenges related to environmental pollutants. This article describes heavy metal pollutants, recovery of oil from wastewater, etc. This article will also focus on the carbon-based nanohybrid, which can be used for the environmental recovery strategies of polluted areas. In particular, this article will give more attention towards the recent method developed and method to capturing heavy metal using silver fabricated reduced graphene oxide nanohybrid for the application of heavy metal capture and separation of oil water.
