Recovery of rhenium(VII) from synthetic leaching solutions of uranium ore using ionic liquid modified cellulose microsphere adsorbents

Effective adsorption of perrhenate ions on the filamentous sheath-forming bacteria, Sphaerotilus montanus, Sphaerotilus natans and Thiothrix fructosivorans

“…The comparison suggests that this bioproduct adsorbs comparable amounts of perrhenate anions with divalent lead or zinc cations. Amongst the synthetic materials, larger capacities than on S. natans are found for various adsorbents prepared by state of art preparation techniques (Chui et al, 2021; Dong et al, 2020; Gaete et al, 2019; Shan et al, 2019; Weng et al, 2021). They usually require relatively expensive reagents and complex preparation, unlikely the dried metabolite products of bacteria.…”

Radiation synthesis of binary poly(ionic liquid) functionalized silica-based materials for selective adsorption of ReO4− as analogue of TcO4− from simulated radioactive wastewater

“…À removal, such as cellulose, 30 silica, [31][32][33][34][35] chitosan, 36 and COFs. 15,37 All the mentioned adsorbents were functionalized by a single ionic liquid.…”

“…29 Ionic liquids exhibited excellent extraction performance towards Re and Tc in liquid–liquid extraction, but their application is restricted due to their liquid form. Therefore, ionic liquids employed as functional monomers have been grafted onto different substrates for TcO 4 − removal, such as cellulose, 30 silica, 31–35 chitosan, 36 and COFs. 15,37 All the mentioned adsorbents were functionalized by a single ionic liquid.…”

Efficient separation and recovery of Re(VII) from Re/U bearing acidic solutions using aminotriazole modified cellulose microsphere adsorbents

“…Cellulose is a naturally available material that is derived various sources of plants by photosynthesis. Cellulose has been described as a cost-effective and environmentally friendly adsorbent for the recovery of precious metals due to its abundance, low cost, biocompatibility and renewability (Guo et al 2018;Dong et al 2020). However, due to the lack of functional groups, the adsorption capacity of natural cellulose is quite poor, limiting its widespread application.…”

“…Heqing Tang et al reported that ReO 4 − could be selectively adsorbed onto chitosan-based ionic gel beads wrapped with methyl-trioctyl ammonium chloride in the presence of MoO 4 2− (Li et al 2020). However, there are few papers concerning rhenium extraction from uranium ore leachates (Dong et al 2020;Hua et al 2020). It was reported that the pH of underground uranium ore leachates mainly varied between 2 and 3 (Abisheva et al 2011).…”
