Various Green Nanomaterials Used for Wastewater and Soil Treatment: A Mini-Review

The industrial intervention had a profound impact on our environment and the amount of damage it has bestowed is in the form of polluted water and solid waste accumulation. With upgradation of technologies in the industrial upfront there is also an increase in the robust nature of industrial waste. Keeping in view of the various environmental aspects, advanced techniques were developed by the inculcation of nanotechnology. Among the diverse technologies that have gained prominence is the use of nanoparticles as a medium to monitor and treatment process. One of them is the use of organic techniques, i.e., the use of nano-chitosan. The review article focuses on the new data pertaining to the study and improvement of various nano-scale treatment technologies implemented for wastewater treatment with an environment friendly biodegradation. The eradication of harmful toxicants is an exhaustive process, but this is required to invigorate the sustainable development. Various strategies were promulgated but the inculcation of nanomaterial provided a low-cost, efficient and simple method for removal of contaminants by adsorption. These nanomaterials provide the best adsorbent due to its simple structural properties that provide a better surface area with high absorption capacity. This comprehensive review gives a glimpse of the various green and other nanotechnologies used for wastewater and contaminated soil treatments.
