The Role of Biocomposites and Nanocomposites in Eliminating Organic Contaminants from Effluents
AI summary Read the abstract
Not relevant to microplastics — this review evaluates biocomposite and nanocomposite sorbents for removing heavy metals, dyes, and hydrocarbons from industrial wastewater, comparing adsorption mechanisms and recyclability.
Many contaminants such as heavy metals, dyes and hydrocarbon compounds are annually generated by industrial activities and discharged into water sources. They have destructive impacts on the environment. To eliminate these toxic contaminants from aqueous media, sorption can be considered a proper and efficient process, as it has indicated high efficiency for removing organic contaminants. This paper entails a comprehensive evaluation of different organic pollutants, pros and cons of the sorption process in removing these pollutants, comparing different types of adsorbents and investigating the recyclability of different types of composites. Moreover, the sorption mechanism and kinetic behavior of organic contaminants are investigated using biocomposites and nanocomposites. Moreover, the future perspectives of biocomposites and nanocomposites in eliminating organic compounds are discussed. Based on investigations, a large number of nanocomposites have been utilized for removing organic contaminants with high performance so far, including SiO2/MnFe2O4/ZIF-8 MOF, magnetite/MWCNTs, nano zerovalent iron, barium/Cobalt/polyethylene glycol (PEG), graphene oxide/Fe3O4, kaolin/CuFe2O4 and Fe3O4@UiO-66. Moreover, polyaniline/sodium alginate/Oscillatoria filamentous cyanobacterium biomass, cow bones/zeolite/coconut biocomposite and AC derived from melamine and sucrose are excellent biocomposites in the removal of organic pollutants. Moreover, the reusability study shows that poly(N-isopropylacrylamide)/Fe3O4 and corn stalk biomass/chitosan/Fe3O4 biocomposites have significant stability compared to other composites in the elimination of organic pollutants.

A critical review of microplastics and nanoplastics in wastewater: Insights into adsorbent-based remediation strategies
AI summary Read the abstract
This review analyzes research on removing microplastics and nanoplastics from water using materials that absorb the particles, finding that adsorption is the most widely studied removal method. Carbon-based and metal-based materials currently dominate the research, but plant-based (biopolymer) adsorbents are gaining attention because they are biodegradable and non-toxic. Better removal technologies are critical because conventional water treatment often fails to capture the smallest plastic particles that pose the greatest risk to human health.
