A comparative review of the adsorption efficiency and performance variances of metal oxide nanoparticles and pristine carbon nanotubes for Pb
Review in Discover nano, 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
Lead (Pb²⁺) contamination in aquatic systems poses a major threat to human health and environmental safety. Conventional remediation techniques such as chemical precipitation and ion exchange are often constrained by high operational costs, poor efficiency at trace concentrations, and secondary pollution. Nanotechnology has introduced materials like carbon nanotubes (CNTs) and metal oxide nanoparticles (MONPs) with superior physicochemical reactivity for Pb²⁺ removal. This review highlights recent advances (2002-2025) in adsorption-desorption behaviour of Pb²⁺ on MONPs and pristine CNTs, focusing on synthesis, surface properties, adsorption mechanisms, reusability, and toxicity. Reported findings reveal that MONPs, including Fe₃O₄, ZnO, MgO, and CuO, exhibit outstanding adsorption capacities (up to 1980 mg g⁻¹ for MgONPs), surpassing those of CNTs which usually range between 10 and 250 mg g
