Summary: In recent years, mixed matrix membranes (MMMs) have become increasingly popular in separation processes due to their outstanding properties. These membranes combine the advantages of both polymer continuous and nanoparticle dispersion phases. Block copolymers like poly(ether-block-amide, PEBA) are considered excellent materials for membrane synthesis. This study provides an overview of PEBA membranes doped with two different aminocompounds at various concentrations and their impact on CO2 sorption and separation. Most samples showed improved CO2 sorption compared to pristine PEBA, with the effect strongly dependent on concentration. The most significant changes were observed in the MMM doped with 2.5% TEPA or 1% HDA. Samples were also tested for the separation efficiency of a binary CO2/CH4 mixture.

Summary: Three-component mixed-matrix membranes consisting of a polymerized room-temperature ionic liquid, a room-temperature ionic liquid, and a zeolite were synthesized and evaluated for CO2/CH4 permeability under various pressure and temperature conditions. The study found that under certain conditions, CO2-induced matrix swelling may lead to delamination of the matrix from zeolite particles.

Summary: In this study, Ultem and NaX zeolite were used to fabricate mixed matrix membranes for CO2 separation. The optimized MMM exhibited a CO2/N-2 selectivity of 34 and a 45% increase in CO2 permeability compared to the pristine membrane. These improvements were attributed to the surface diffusion mechanism of zeolite X and the reversible reaction between Ni2+ ions and CO2 molecules.

Zeolite and zeolite-based mixed matrix membrane (MMM) have shown promising potential in CO2/CH4 separation due to their thermal and chemical stability. Various modification methods have been employed to enhance the CO2/CH4 selectivity of zeolite-based MMM, with ionic liquid and silane methods showing the most significant improvements. Additionally, zeolite-based MMM has potential applications in water purification, biomedical fields, and gas separation.

Summary: Industrial wastewaters contaminated with heavy and toxic metals pose serious risks to human health and other forms of life. The performance of biochar in removing heavy metals has been widely recognized, and there is a need for efficient computational methods to predict its biosorption performance. In this study, the performance of four machine learning methods was evaluated using data from heavy metal adsorption experiments. All four models showed good predictive performance, with the CSA-LSSVM model performing the best. Sensitivity analysis revealed the key parameters for heavy metal removal by biochar. The findings of this research enhance understanding of effective remediation of hazardous chemicals in water resources.

Summary: The focus of current environmental science is on addressing the challenge of separating acid gases, and scientists are developing high-performance membranes to transport gases effectively. Mixed matrix membranes (MMMs), which contain inorganic nanoparticles dispersed within the polymer matrix, are gaining popularity as an alternative to traditional membranes. This study investigated the morphological properties and gas transport properties of polyurethane (PU) membranes treated with titanium dioxide (TiO2) functionalized with methylene diisocyanate (MDI). The results showed that MDI modification improved TiO2 dispersion in the PU matrix, leading to a more uniform and compact membrane structure, and the incorporation of TiO2 enhanced CO2/N2 selectivity in the PU matrix.

Summary: Novel chitosan-tailored graphene oxide (CSGO)-embedded poly(ether-b-amide) (PEBA) thin film nanocomposite (TFN) membranes have been successfully fabricated and coated on ultraporous polyethersulfone. The green nanofillers were synthesized by covalent functionalization of GO with carbohydrate polymer chitosan and incorporated into the PEBA selective layer. The structural studies confirmed the appropriate filler dispersion and improved hydrophilicity of the TFN membranes. Moreover, the membrane loaded with 0.1 wt% of CSGO exhibited the highest permeate flux and improved antifouling performance.
