Sorption of Radionuclides: A Review”

摘要

Chitin, chitosan, chitin- and chitosan- derivatives, living and dead fungi, and modified fungal biomass have been used for their ability to sorb metals, radionuclides, dyes and ions from water, waste water, soil and other contaminated sources. These sorbents are based on chitin, contain a large number of functional groups such as hydroxyl and amino groups enabling them to exhibit high sorption potential. Chitin and related-derivatives owing to their low cost, high sorption capacities, ease of use and ability to regenerate have found significant acceptance for removal of radioactive pollutants. Biosorption using fungi has been achieved with surprising success. This review includes fungi from divisions of Ascomycota, Basidiomycota and Zygomycota due to the presence of chitin and chitosan as significant components of their cell walls. In this review, an extensive list of chitin, chitosan, chitin- and chitosan- derivatives, living and dead fungi, and modified fungal biomass from vast literature was reviewed and their sorption capacities for a variety of radionuclides as available are shown.
