Tailoring activated carbon and carbon black adsorbents for efficient PAH removal.

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
Polycyclic aromatic hydrocarbons (PAHs) in industrial effluents pose severe environmental and health risks due to their carcinogenicity, bioaccumulation potential, and resistance to conventional treatment. This study investigated the effects of nitric acid functionalization and metal ion-exchange on the structural properties and anthracene adsorption performance of activated carbon (AC) and carbon black (CB) as representative carbon-based adsorbents. Nitric acid treatment of CB enhanced mesopore development and introduced oxygen-containing functional groups, improving anthracene removal efficiency from 69 to 74% at a 200:1 feed-to-carbon ratio. Conversely, acid treatment of AC reduced removal efficiency from 60 to 50%, attributed to critical micropore volume effected as confirmed by Brunauer-Emmett-Teller (BET) surface area. Metal ion-exchange reduced adsorption performance in both materials, due to nanoparticle agglomeration and surface area while CB-Ni and CB-Zn retained moderate removal efficiencies of 62% and 66%, consistent with better metal dispersion. A strong linear correlation (R
