BACKGROUND: Developing new materials for separating Sr 2+ ions from aqueous solutions is significant. Metal-organic frameworks are regarded as excellent adsorption materials due to their high specific surface area and abundant adsorption sites. In this work, a novel UiO-66-(COOH) 2 -based mixed matrix membrane (MMM) was prepared by combining UiO-66-(COOH) 2 with polyethersulfone (PES) for separating Sr 2+ . RESULTS: The MMMs were characterized using scanning electron microscopy, Fourier transform infrared spectroscopy and water contact angle and water flux measurements. Various contents (0-2.5 wt%) of UiO-66-(COOH) 2 were blended into PES membranes. The results showed that incorporating UiO-66-(COOH) 2 significantly increased membrane porosity and water flux, and reduced contact angle. The membrane (M4) that contained 2.0 wt% UiO-66-(COOH) 2 exhibited an excellent morphology and the highest Sr 2+ uptake capacity (111.9 ∼g cm −2 ). Adsorption kinetics and isotherms showed that the nature of the adsorption of the membrane towards Sr 2+ was chemisorption, homogeneous and monolayer. Compared with the adsorption capacity of UiO-66-(COOH) 2 towards Sr 2+ in adsorption packed column, these values of M4 decreased by about 75% during membrane filtration. The rejection performance of MMMs increased with increasing UiO-66-(COOH) 2 content. Breakthrough curves of MMMs were not correlated with flow rate in the range of 10-180 mL h −1 . The presence of Ca 2+ and Mg 2+ ions did not obviously affect the separation of Sr 2+ , but Pb 2+ had a significant influence. Furthermore, after five adsorption-desorption experiments, the regeneration remained at about 95% of initial values. CONCLUSIONS: The MMMs showed good adsorption capacity for Sr 2+ and exhibited favorable reusability and stability.

“…2 Hence, it is essential to treat wastewater by removing HMIs. Numerous methods have been employed for this purpose, such as ion exchange, 3 adsorption, 4 chemical precipitation, 5 and membrane separation. 6 Due to its high adsorption effectiveness and simplicity of operation, adsorption is an excellent option for eliminating low-concentration HMIs from aqueous solutions.…”
