“…The presence of phenolic compounds in drinking water has a detrimental impact on human and animal health [ 5 , 6 ]. Therefore, efforts have been made to minimize the content of these harmful pollutants by developing appropriate elimination methods, including (photo)catalytic oxidation [ 7 , 8 , 9 , 10 ], biodegradation [ 11 , 12 , 13 ], and membrane technologies [ 14 , 15 ]. Particularly significant benefits, however, are achieved through the use of adsorbents, which enable the quick, easy, and effective removal of phenols, for example, in batch or flow systems.…”

In this work, a synthesis and activation path, which enabled the preparation of spherical activated carbon from a lignin precursor, characterized by high adsorption capacity in the removal of phenolic compounds from water, was successfully developed. Two industrial by-products, i.e., Kraft lignin and sodium lignosulfonate, were used to form spherical nanometric lignin grains using pH and solvent shift methods. The obtained materials became precursors to form porous activated carbons via chemical activation (using K2CO3 or ZnCl2 as activating agents) and carbonization (in the temperature range of 600–900 °C). The thermal stabilization step at 250 °C was necessary to ensure the sphericity of the grains during high-temperature heat treatment. The study investigated the influence of the type of chemical activator used, its quantity, and the method of introduction into the lignin precursor, along with the carbonization temperature, on various characteristics including morphology (examined by scanning electron microscopy), the degree of graphitization (evaluated by powder X-ray diffraction), the porosity (assessed using low-temperature N2 adsorption), and the surface composition (analyzed with X-ray photoelectron spectroscopy) of the produced carbons. Finally, the carbon materials were tested as adsorbents for removing phenol from an aqueous solution. A conspicuous impact of microporosity and a degree of graphitization on the performance of the investigated adsorbents was found.

“…The comparison of membrane technologies with other purification processes such as coagulation (Girish et al 2023;Kyrii et al 2020), adsorption Kyrii et al 2023;Dontsova et al 2022), photocatalysis (Kutuzova et al 2022;Ge et al 2021) and others (Alkhadra et al 2022;Grzegorzek et al 2023) show their greater versatility, which can be successfully applied to solve problems of any complexity, not only in the field of water treatment, but also, for example, in separation processes (Alardhi et al 2023), extraction of valuable components from liquid media (Siagian et al 2023), purification and reuse of rainwater (Liu et al 2021), and solving problems in the food industry (Suliman et al 2023).…”

The article is devoted to the synthesis of ceramic membranes based on silicon carbide and the study of their mechanical, electrical, and antibacterial properties. SiC-based ceramic membranes have a few advantages, namely high surface hydrophilicity, good water permeability and negative surface charge, which leads to better performance during their operation. The effect of carbonate type and addition of liquid glass on the physicochemical properties of ceramic membranes was investigated using diffraction analysis and scanning electron microscopy. It was found that regardless of the carbonate type, only two phases can be identified: the main phase in the original mixture is silicon carbide and an additional phase added to the mixture is corundum. The transport properties obtained (9.03–18.66 cm3/(min·cm2)), and the results of electron microscopy indicate the macroporosity of ceramic membranes based on silicon carbide (13–20 µm). Ceramic membranes of high strength (16.3–46.8 MPa) were obtained. Studies on antibacterial properties have shown that SiC-based ceramic membranes do not exhibit antibacterial properties. The additional modification of ceramic membranes with titanium oxide has given ceramic membranes based on silicon carbide antibacterial properties, as evidenced by the inhibition of the growth of gram-negative bacteria, the effectiveness of which depends on the number of selective layers based on TiO2 applied. The results of this study are useful to enrich the knowledge of the production of silicon carbide membranes and are aimed at the future research and development of selective membranes (micro- and ultrafiltration) based on them.

Colour is typically the initial pollutant identified in wastewater. Membrane separation represents a novel approach to separation processes, with expectations of supplanting many traditional separation systems. The aim of this study is to investigate polymer inclusion membranes (PIMs) consisting of tri octyl methyl ammonium chloride as the carrier, tributylphosphate as the modifier, poly-vinyl chloride as the base polymer and 2-Nitro phenyl pentyl ether as the plasticizer for removing an acid dye (Red Erionyl A-3G) from aqueous solution. The dye adsorption on the membrane surface and its transition to the stripping phase was achieved by placing the membrane between two glass cells. Changing the stripping solution ensured both adsorption on the membrane surface and the transfer of all the dye to the stripping stage. Using a mixture of 0.8 M salicylic acid and 0.8 M NaOH, along with stirring at 1000 rpm during the stripping phase, extraction efficiency reached 98% in the feed phase and 53% in the stripping phase. When 1 M NaOH solution was employed as the stripping solution, the membrane absorbed all the dye within 10 minutes, but there was no transition to the stripping phase. The membrane has a durability of 2 days. Graphical abstract
