“… 75 Li et al also found that UO 2 2+ could be removed by coordination interactions between UO 2 2+ and carboxyl/amino groups on the MSONs, as illustrated in Figure 4 b. 98 Similarly, the existence of Co-OH groups on ZIF-67 coordinating with uranyl ions was confirmed by Fourier transform infrared (FTIR) and X-ray photoelectron spectroscopy (XPS) spectra, thus explaining the great capacity for the adsorption of U(VI) ( Figure 4 c). 76 Based on the results shown above, functional groups introduced into MOFs played an extremely important role in coordinating with U(VI).…”

“…The experiment results indicated that these five coexisting ions with extremely high concentrations (250, 500, and 1000 mg/L) had no essential effect on U(VI) removal by MSONs-5 ( Figure 3 b), which revealed that MSONs-5 could be regard as a powerful adsorbent to capture U(VI). 98 The effect of the coexisting ions (Ca 2+ , Mg 2+ , Hg 2+ , and Zn 2+ ) on the removal of U(VI) by a Cu 3 (btc) 2 encapsulating H 3 PW 12 O 40 hybrid 94 , 101 , 116 materials (HKUST-1@H 3 PW 12 O 40 ) was also investigated. The results showed that the adsorption efficiency of U(VI) did not significantly change in the existence of these coexisting ions, which implied that HKUST-1@H 3 PW 12 O 40 could effectively and selectively adsorb U(VI) from aqueous solution with other metal ions.…”

The steady supply of uranium resources and the reduction or elimination of the ecological and human health hazards of wastewater containing uranium make the recovery and detection of uranium in water greatly important. Thus, the development of effective adsorbents and sensors has received growing attention. Metal–organic frameworks (MOFs) possessing fascinating characteristics such as high surface area, high porosity, adjustable pore size, and luminescence have been widely used for either uranium adsorption or sensing. Now pertinent research has transited slowly into simultaneous uranium adsorption and detection. In this review, the progress on the research of MOF-based materials used for both adsorption and detection of uranium in water is first summarized. The adsorption mechanisms between uranium species in aqueous solution and MOF-based materials are elaborated by macroscopic batch experiments combined with microscopic spectral technology. Moreover, the application of MOF-based materials as uranium sensors is focused on their typical structures, sensing mechanisms, and the representative examples. Furthermore, the bifunctional MOF-based materials used for simultaneous detection and adsorption of U(VI) from aqueous solution are introduced. Finally, we also discuss the challenges and perspectives of MOF-based materials for uranium adsorption and detection to provide a useful inspiration and significant reference for further developing better adsorbents and sensors for uranium containment and detection.

Layered zirconium phosphate (ZrP) is a versatile material with phosphate (POH ) groups able to exchange inorganic and organic cations or to intercalate basic molecules. The present review deals with the use of this material as a sorbent for heavy metal cations or dye molecules in wastewater treatments. The possibility to combine ZrP with polymers or other inorganic materials, in order to have suitable systems for real and large scale applications, was investigated, as well as the combination with photocatalytic materials to obtain hetrogeneous photocatalysts for the capture and photodegradation of organic dye molecules.

“…Generally, the uranium removal rate by sorption is mainly influenced by physical/chemical properties of adsorbents (i.e., pore structure, surface groups), uranium concentration, pH, etc. ( Kataria and Garg, 2018 ) Biochar ( Sun et al, 2013 ; Sun et al, 2017 ; Kong et al, 2020 ), graphene ( Zhao et al, 2019 ), calixarene ( Fang-Zhu et al, 2019 ), MOFs ( Li et al, 2020 ), and mesoporous silicon ( Jiang et al, 2020 ) were used as sorption materials. Among them, biochar has been verified as an important sorption material for uranium recovery or removal from aqueous solution ( Jin et al, 2018 ; Li et al, 2019a ), due to its simple preparation process, lower price, higher temperature resistance, radiation resistance, higher stability to almost all kinds of acidic and alkali environments, nontoxic, and environmentally friendly nature ( Zhao et al, 2017 ; Pu et al, 2019 ).…”

Excess sludge (ES) treatment and that related to the uranium recovery from uranium-containing wastewater (UCW) are two hot topics in the field of environmental engineering. Sludge-based biochar (SBB) prepared from ES was used to recover uranium from UCW. Excellent effects were achieved when SBB was modified by acetic acid. Compared with SBB, acetic acid-modified SBB (ASBB) has shown three characteristics deserving interest: 1) high sorption efficiency, in which the sorption ratio of U(VI) was increased by as high as 35.0%; 2) fast sorption rate, as the equilibrium could be achieved within 5.0 min; 3) satisfied sorption/desorption behavior; as a matter of fact, the sorption rate of U(VI) could still be maintained at 93.0% during the test cycles. In addition, based on the test conditions and various characterization results, it emerged as a dual effect of acetic acid on the surface of SBB, i.e., to increase the porosity and add (−COOH) groups. It was revealed that U(VI) and −COO− combined in the surface aperture of ASBB via single-dentate coordination. Altogether, a new utilization mode for SBB is here proposed, as a means of efficient uranium sorption from UCW.
