Exploration of electrospinning hemp/polyacrylonitrile composite fiber membrane and dye adsorption capabilities.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Textile printing and dyeing wastewater has complex water quality and causes great harm. As a common pollutant, the cationic methylene blue dye is harmful to health. Therefore, adsorption technology plays a crucial role in wastewater treatment. To study the application of hemp/polyacrylonitrile nanocomposite fiber membranes in dye adsorption, this study employed electrospinning technology. This study used electrospinning to prepare hemp/polyacrylonitrile nanocomposite fiber membranes for dye adsorption. Hemp fibers were dissolved in LiCl/DMAc, blended with polyacrylonitrile solution, and electrospun after single-factor optimization. The results show that the hemp/polyacrylonitrile composite fiber membrane has a uniform diameter distribution, good hydrophilicity, and excellent mechanical and physical properties. The particulate matter filtration test reveals that the membrane’s filtration efficiency can reach 99.97%. The adsorption of methylene blue by the hemp/polyacrylonitrile composite fiber membrane is more consistent with the pseudo-second-order kinetic model and the Langmuir adsorption isotherm model, indicating that it is mainly dominated by chemical adsorption. The adsorption process is a spontaneous endothermic reaction, and a higher temperature is more conducive to adsorption, with an adsorption capacity of up to 75.85 mg/g. The simple method yielded membranes with excellent dye adsorption and particulate filtration performance.
