Graphene-based composites for heavy metal adsorption: a review on synthesis, mechanisms, and influencing factors.
Review in Environmental science and pollution research international, 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
Heavy metal contamination in aquatic ecosystems is a global concern due to its toxicity, persistence, and potential for bioaccumulation. Effective removal is therefore essential. Among other techniques, adsorption is the most reliable and prevalent method of water purification. Graphene-based adsorbents exhibit significant advantages, including high specific surface area, small particle size, excellent mechanical properties, abundant functional groups, and high adsorption efficiency, making them promising materials for heavy metal removal from aqueous solutions. This article reviews recent advances in graphene and its derivative composites for heavy metal adsorption. It discusses structural features, adsorption mechanisms, synthesis methods, and the historical development of these composites. Key factors influencing adsorption capacity-such as temperature, pH, adsorbent dosage, contact time, initial metal concentration, organic ligands, and coexisting ions-are also examined. Additionally, adsorption thermodynamics and regeneration behavior are evaluated, and future research directions for practical applications are outlined.
