Insights into Kinetics and Thermodynamics for Adsorption Methylene Blue Using Ecofriendly Zeolites Materials.
Article in ACS omega, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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
Different materials have been used as adsorbents for removing micropollutants from industrial effluents, with vegetal-derived activated carbon being widely reported for dye removal, especially methylene blue (MB). However, its high cost and environmental concerns have driven the search for alternative adsorbents. Beyond developing new materials, understanding the interaction mechanisms between adsorbents and adsorbates is crucial. In this investigation, sodium (NaZ) and protonic (HZ) zeotypes were synthesized using diatomaceous earth (DE) residue as a silicon source and applied to MB dye adsorption. Batch experiments investigated adsorption rates, mechanisms, and thermodynamic spontaneity. The results showed rapid adsorption kinetics, with equilibrium achieved in about 5 min, following the Avrami model. The Weber and Morris model highlighted that the boundary layer significantly affects film diffusion and intraparticle diffusion. The adsorption process reached equilibrium governed by the Freundlich model, with favorable adsorption behavior for all adsorbents (nF values between 1 and 10). Additionally, the enthalpy values were found to be +39.66, + 5.70, and +21.79 kJ mol
