Removal of Pollutants from the Environment Using Sorbents and Nanocatalysts
Modernization and progress over the years have resulted in more environmental pollution. Some of the major factors responsible for pollution are industries, vehicles, the increase in the population, and urbanization. In order to overcome environmental pollution problems, a number of removal techniques are available. Recently, many reports have been published about the preparation of nano-materials for reducing pollution in the environment. In this regard, many kinds of materials, such as sorbents and catalysts, have been prepared for developing these processes. In this chapter, hydrodesulfurization (HDS) as an important process for removal of sulfur compounds from fuels is studied. In addition, elimination of heavy metals from waste water and separation of the dangerous radionuclides from liquid nuclear waste are investigated.
