The book is a comprehensive deep-dive into the developments and advancements of emerging carbon-based nanocomposites for wastewater applications. Science and technology development are tackling one of the world's most pressing concerns—water contamination and effective treatment. Carbon-based nanocomposites have emerged as one of the leading materials in this treatment push because of their properties and high ability for the catalytic degradation of contaminants from aqueous segments. The 10 chapters in this timely book cover the follows areas: Carbon-based nanocomposites for remediation of heavy metals and organic pollutants from wastewaterFunctional green carbon nanocomposites for heavy-metal treatment in waterGreen nanocomposites and applications in environmentally-friendly carbon nanomaterialsCarbon-based nanocomposites as heterogeneous catalysts for organic reactions in environment-friendly solventsCarbon-based polymer nanocomposite applicationsBiochar-based adsorbents for the removal of organic pollutants from aqueous systemsCarbon nanomaterial-based green nanocompositesThe removal of trihalomethanes from water using nanofiltration membranesNanocomposite materials as electrode materials in microbial fuel cells for the removal of water pollutantsPlasmonic smart nanosensors for the determination of environmental pollutants.
