The development of modern industry will generate more and waste containing metal ions. It is necessary to take appropriate measures recover these ions, whether from the perspective environmental protection or improving economic benefits. So far, scientists have studied many methods for recovering Among methods, adsorption membrane separation received widespread attention due their own characteristics. Combining can better leverage respective advantages improve ability This review, therefore, focuses on synergistic recovery ions by methods. article first briefly explains theoretical principles synergy, then several technologies that in different chapters. In chapters, technology introduced, followed situation progress application with technology. Then, compares elaborates disadvantages above technologies, finally summarizes looks forward being used solve difficulties challenges industrial application.

Abstract A mechanistic modelling of the adsorption processes onto individual minerals presenting in near- and far-fields can greatly enhance credibility long-term safety assessments granite-based geological repositories. In this study, titration U(VI) characteristics chlorite, one major rock fractures, have been studied. Potentiometric curves at two ionic strengths (0.1 0.4 mol/L NaCl) are successfully interpreted by considering protonation/deprotonation reactions on generic edge sites (≡SOH) framework a non-electrostatic surface complexation model (SCM). The chlorite was reached after 24 h, kinetics be described pseudo-second-order model. SCM with three complexes (≡SOUO 2 + , ≡SO(UO ) 3 (OH) 5 7 2− set up based pH edges equilibrium absence CO . Additional, experimental data measured as function concentration, solid-to-liquid ratio carbonate concentration were well reproduced proposed Finally, parallel experiments conducted using X-ray photoelectron spectroscopy (XPS) to analyze variation species speciation different values. good agreement between prediction XPS analysis demonstrates reliability predicting quantifying radionuclides retention chlorite.
