Development of sustainable extraction method for long-lived radioisotopes, 133Ba and 134Cs using a potential bio-sorbent

Coupling Plant Biomass Derived from Phytoremediation of Potential Toxic-Metal-Polluted Soils to Bioenergy Production and High-Value by-Products—A Review

“…For instance, Tiwari et al [126] reported the current phytoremediation situation in India, where the availability of different phytoremediator trees is abundant, for example, Azadirachta indica, Acacia nilotica, Prosopis juliflora, Terminalia arjuna, Pongamia pinnata, and Eucalyptus tereticornis. Special interest is the use of Azaridachta indica and Acacia nilotica not only for their use in traditional medicine, personal care, and the presence of biologically active compounds [127] but also because of restoration of eroded soils and the phytoremediation potential, removing organic compounds [128,129], radionuclides [130], and toxic metals [122,131,132]. The studies report using seeds of A. indica from phytoremediation to produce ethanol from biomass fermentation and biodiesel via base-catalyzed transesterification.…”

Synergistic Aqueous Biphasic Separation of No‐Carrier‐Added 71,72As from a Gallium Oxide Target Using Green Tea Polyphenols

“…Earlier we have successfully used nature resourced chemicals (NRC) in various radiochemical separations. Few examples of NRCs are: hesperidin obtained from orange peel, [9] potato peels, [10,11] conarachin and arachin extracted from groundnut, [12,13] piperine extracted from black pepper, [14] seed protein from Bakul tree, [15] Mung beans, [16] albumin from egg, [17] etc., all of which were successfully applied to develop radiochemical separation techniques. Presence of hydroxyl groups in the structure of catechins helps them to scavenge reactive oxygen species such as superoxide radicals, singlet oxygen, hydroxyl radicals, nitric oxide, nitrogen dioxide, and peroxynitrite, all of which play important roles in free radical induced carcinogenesis.…”
