Biosorption of Uranium and Rare Earth Elements Using Biomass of Algae

Abstract

In order to investigate the behavior of rare earth elements (REEs) and uranium (U) in marine organism, the concentrations of REEs and U in some brown algae samples taken on the coast of Niigata Prefecture were determined. In addition, laboratory model experiment to uptake these elements using living and dried algae (Undaria pinnatifida and Sargassum hemiphyllum) was also carried out to survey the uptake and bioaccumulation mechanism of REEs and U in algae. Consequently, the following matters have been mainly clarified. (1) The order of the concentration of REEs for each organ in Sargassum hemiphyllum is “main branch” > “leaf” > “vesicle,” however for U, the order is “leaf” > “vesicle” > “main branch.” (2) The concentration of REEs in Sargassum hemiphyllum may be strongly affected by suspended solid in seawater. (3) The uptake and/or accumulate mechanism of REEs in brown algae may be different from that of U.

Recent International R&D Activities in the Extraction of Uranium from Seawater

“…Previous studies have shown that the concentration factor of biomass such as algae for uranium in seawater is about 200 (18), which is too low for practical applications. Development of Innovative biomaterials with engineered protein (such as that shown in Figure 12 could significantly increase the concentration factor and make bio-collection practical.…”

“…The laboratory studies cover the preparation of amidoxime-based adsorbents, the equilibrium of the uranium uptake, and the kinetics and mechanism of the extraction of uranium from seawater (4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16). Collection of uranium with chitosan-resin and biomass such as algae was also performed (17,18). The marine experiments were performed by using two types of collection systems: the stack system and the braid system (19,20).…”

Occurrence of uranium, thorium and rare earth elements in the environment: A review

“…Plants and aquatic organisms have been reported to accumulate U from soils and water in the range of 0.08-3500 mg kg −1 (Huang et al, 1998;Dienemann et al, Frontiers in Environmental Science frontiersin.org Chang et al, 2005;Sakamoto et al, 2008;Viehweger and Geipel, 2010;Caldwell et al, 2012;Cordeiro et al, 2016;Boryło et al, 2017;Li C et al, 2019;Bergmann and Graca, 2020). Hyperaccumulation of U from contaminated sites has been reported for several plant species and aquatic organisms (Dienemann et al, 2002;Chang et al, 2005;Viehweger and Geipel, 2010;Caldwell et al, 2012;Li C et al, 2019;Bergmann and Graca, 2020).…”
