An experimental technique was developed for the production of tableted nanostructured fibrous enterosorbent for medical applications using a nanostructured activated carbon fiber material of solid-phase pyrolytic origin, created by our research team. The properties of the main active ingredient in the pills, as an effective adsorbing component, were studied. The porous structure parameters were examined with the desiccator method based on the absorption of benzene vapors, while the specific surface area was analyzed with the Brunauer–Emmett–Teller (BET) method. Spectrophotometric methods were employed to determine the concentration of the sorbate in solutions. The microstructure of the samples was studied using a scanning electron microscope (Superprobe-733 X-ray microanalyzer, JEOL, Japan). Energy-dispersive X-ray analysis provided data on the chemical composition and biocompatibility of the samples, serving as an integral indicator. Conditions for the key stages in the enterosorbent production process were experimentally tested. The influence of different types of binders on the process properties of the tablet charge and on the characteristics of test enterosorbent pills was analyzed. The novelty of the developed process was the use of material with special characteristics, promoted by bound carbon nanoforms present in its structure, for enterosorbent production. Improvements in the process operations were proposed, such as decreasing the compaction speed and simultaneously increasing the time the tablet charge was kept under pressure, leading to the redistribution of strains. It was proposed that the compaction process be conducted using punches with a flat surface of purity class 10 to prevent sticking. Therefore, our research team developed tableted enterosorbent with typical features of its main component—nanostructured activated fibrous carbon material—as an effective adsorbent for a relatively wide range of different compounds.
