Abstract
In this work we studied adsorption of methylene blue in the range of concentrations 0.047–1.5 mg/ml on adsorbent materials: nanodiamond powders, activated spherical carbon SCS030, and three types of activated carbon fibrous material (ACFM). These materials have different morphology of particles and were studied with scanning electron microscopy. SEM-images have shown that ACFM fibers have cylindrical form with some impurities on surface, SCS030 looks like highly porous spheres, nanodiamond powder form agglomerates. Analyzing adsorption curves, we compared adsorption properties of these materials taking into account that they were synthesized by different methods and have different porosity and surface area. Based on obtained adsorption isotherms it is possible to make a conclusion about perspective to use activated carbon fibrous material for a broad range of purification operations, adsorption of toxins and as well as bandages during bleeding. SCS030 could be applied for more precise selective blood filtration. Nanodiamonds could be recommended to use as platform for drug-delivery systems.
Keywords: adsorption, methylene blue, nanodiamond, activated spherical carbon SCS030, activated carbon fibrous material

MXenes potential applications include sensors, wound healing materials, and drug delivery systems. A recent study explored how different synthesis methods affect the safety and performance of MXenes. By comparing etching conditions and intercalation strategies, researchers discovered that fine-tuning the surface chemistry of MXenes plays a crucial role in improving biocompatibility. These results provide practical guidelines for developing safer MXenes and bring the field one step closer to real biomedical applications.
