1 · What the graph read from it

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.

2 · The registry

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

This study reports the preparation of granular ternary micro-electrolysis materials and their effectiveness in removing the emerging contaminant PFOA. Al/nZVI/C@F granules were synthesized using a liquid-phase reduction method combined with high-temperature calcination. By comparing the removal of methylene blue dye by granules, the optimum preparation conditions were determined as follows: Fe:C = 5:1, fly ash = 50%, calcination temperature = 800 °C, and holding time = 1 h. Static batch experiments revealed that under optimal conditions (PFOA concentration = 25 mg/L, solid-liquid ratio = 30 g/L, pH = 3, reaction temperature = 15 °C), Al/nZVI/C@F achieved a PFOA removal rate of 97.83%. The removal efficiency of Al/nZVI/C@F (93.90%) was significantly higher than that of commercial iron-carbon (12.75%). After 45 days of dynamic column experiments, the removal efficiency of nZVI/C@F and Al/nZVI/C@F for PFOA (50 mg/L) remained above 60%, demonstrating strong practical application potential. Further adsorption-desorption experiments revealed that nZVI/C@F and Al/nZVI/C@F primarily removed 50 mg/L PFOA through adsorption. For a lower PFOA concentration of 0.5 mg/L, the defluorination rates were 53.2% for nZVI/C@F and 68.9% for Al/nZVI/C@F. High-performance liquid chromatography-tandem mass spectrometry was used to analyze the intermediates formed during PFOA removal, leading to a proposed degradation pathway.
