Prussian blue analogs-based layered double hydroxides for highly efficient Cs+ removal from wastewater

Universal Strategy for Preparing Highly Stable PBA/Ti3C2Tx MXene toward Lithium-Ion Batteries via Chemical Transformation

“…Specifically, due to the smaller solubility of PBA, Ni 2+ and Mn 2+ released from NiMn-LDH combined with [Fe(CN) 6 ] 3− , leading to the nucleation and subsequent growth of NiMn-PBA. 38,39 The presence of 2D host (MXene and GO) effectively restricted the aggregation of PBA crystals because of the strong electrostatic attraction. 40 Ni 0.8 Mn 0.2 -LDH nanosheets can be homogeneously dispersed in water (Figure 2a).…”

“…In comparison with direct transformation of bare LDH, a dramatic decrease in PBA particle size was observed on the 2D host. Specifically, due to the smaller solubility of PBA, Ni 2+ and Mn 2+ released from NiMn-LDH combined with [Fe­(CN) 6 ] 3– , leading to the nucleation and subsequent growth of NiMn-PBA. , The presence of 2D host (MXene and GO) effectively restricted the aggregation of PBA crystals because of the strong electrostatic attraction …”

Novel Zr-Doped Thiostannate Spinning Fiber (Fiber-KZrTS) for Highly Efficient and Renewable Recovery of Cesium and Strontium from Geothermal Water

“…In this study, the Thomas model is introduced to describe and predict the dynamic behavior of the Fiber-KZrTS material in the column. The model is based on Langmuir adsorption and can be written as follows c italict c 0 = 1 1 + exp [ true( k Th v true) false( m q 0 − c 0 v t false) ] where k Th (L/(mg min)) is the Thomas rate constant and q 0 (mg/g) is the adsorption volume.…”

“…In the above formula, K d (L•g −1 ) is the thermodynamic distribution coefficient; T (K) is the thermodynamic temperature of the adsorption process; R (8.314 J•mol −1 •K −1 ) is the ideal gas mole constant; and ΔH (kJ•mol −1 ), ΔG (kJ•mol −1 ), and ΔS (J•mol −1 •K −1 ) are enthalpy change, Gibbs free energy, and entropy change, respectively. 28 The thermodynamic adsorption parameters of KZrTS at 298, 308, 318, and 328 K (ΔH 0 , ΔG 0 , and ΔS 0 ) can be calculated by the slope and intercept of ln K d and 1000/T curves, and the results are shown in Table 1.…”

Novel One-Pot Solvothermal Synthesis of High-Performance Copper Hexacyanoferrate for Cs+ Removal from Wastewater

“…However, the limited direct use of MHCFs made it attractive to immobilize MHCFs onto substrate materials, which severely reduced cesium adsorption capacity. erefore, a variety of approaches have been taken into account to maximize the performance of MHCFs, mainly focusing on the immobilization form or structure of composites [33][34][35][36][37]. An outstanding MHCF could also make a breakthrough in the adsorption performance of composite adsorbents.…”
