<jats:p>In this study, a green and efficient persimmon tannin functionalized polyacrylonitrile fiber (PAN-TETA-PT) was prepared and used to treat U(VI). The influence of pH value, adsorption temperature and time, and fiber material dosage on the adsorption U(VI) of PAN-TETA-PT fibers were investigated, and the kinetics, isotherm, and thermodynamics of fibers were analyzed. When the pH is 6, the temperature is 30°C, and the fiber dosage is 0.2 g·L<jats:sup>−1</jats:sup>, the adsorption rate of PAN-TETA-PT fibers to U(VI) was 96.5%, and the U(VI) adsorption capacity was 159.75 mg/g. The kinetic and isothermal studies show that the adsorption of PAN-TETA-PT fibers to U(VI) is chemisorbed and multilayer adsorption. The thermodynamic analysis reflects that the PAN-TETA-PT is spontaneously endothermic for the adsorbed U(VI).</jats:p>

<jats:title>Abstract</jats:title>
<jats:p>Persimmon tannin modified chitosan (PT-CS) microspheres were synthesized by a water bath method using sodium tripolyphosphate (STPP) as a cross-linking agent for the removal of U(VI) from wastewater. The results showed that the optimal preparation conditions for PT-CS were a ratio of PT to CS mass of 4:1 and a reaction temperature of 80°C. When the initial concentration of U(VI) was 5 mg/L, and the pH value was 1.5, the PT-CS was injected at 0.06 g/L, and the reaction was 2.5 h. The removal rate of U(VI) from water reached 99.2%. The results of the deep removal test of U(VI) from rare earth wastewater showed that the concentrations of U(VI) in the combined wastewater and extraction wastewater were reduced from 4.42 mg/L and 2.12 mg/L to within 0.02 mg/L at pH 2.0, respectively. In contrast, the removal rate of high concentrations of Ca<jats:sup>2+ i</jats:sup>n the wastewater reached 99%, meeting the emission standards of the rare earth industry.</jats:p>

摘要：
Photocatalytic technology is a valid solution for the remediation of wastewater containing uranium. In this study, the synthesis of Z-scheme g-C(3)N(4)/TiO(2) catalysts was made by a thermal synthetic approach for photocatalytic U(vi) reduction. The characterization results revealed the successful synthesis of g-C(3)N(4)/TiO(2) nanostructures. The g-C(3)N(4) surface was uniformly coated with TiO(2) nanoparticles. The depletion of U(vi) in water evaluated the photocatalytic activity of g-C(3)N(4)/TiO(2) under UV light irradiation. The photocatalytic tests showed that g-C(3)N(4)/TiO(2) exhibited more effective photocatalytic activity than the raw materials (1.64 and 56.97 times higher than TiO(2)(P25) and g-C(3)N(4), respectively). Besides, a pseudo-first-order model was followed by the experimental kinetic data for the photocatalytic process. Moreover, g-C(3)N(4)/TiO(2) still presented high photocatalytic activity after four reacting cycles. Based on these experiment results, the improved photocatalytic activity could be attributed to the Z-scheme mechanism, which decreased the recombination of photo-produced electrons and holes. The synthesis of these g-C(3)N(4)/TiO(2) nanomaterials provides a facile and inexpensive method for treating wastewater containing U(vi).

摘要：
Green rust functionalized geopolymer of composite cementitious materials (GR-CCM) was synthesized to improve the adsorption and subsequent stabilization/solidification of chromate in a holistic operating system. The initial pH in solution exhibited the most significant effect on the chromate removal by GR-CCM among three adsorption factors. The maximum monolayer adsorption capacity and theoretical saturation capacity of GR-CCM for Cr(VI) in the acidic condition were 55.01 mg/g and 41.70 mg/g, respectively. Amorphousness brought by loading GR weakened the crystallinity of composite cementitious materials (CCM), which enhanced the adsorption capacity of CCM and boosted the solidification process. The mixed-valent iron species in the GR-CCM not only directly engaged in the adsorption and reduction of chromate also positively strengthened the solidification of Cr species during the whole treatment. This study facilitates the application of GRs on the geopolymer materials and demonstrates the combination of adsorption and immobilization for the treatment of other potential heavy metal contamination.
