Superior-Selective and Complete Recycling of Trace Precious Metals From Wastewater by Magnetic Trilayer Carbon-Aerogels.

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
It is a considerable challenge to selectively recycle precious metals from industrial wastewater and natural waters. Herein, carbon aerogels embedded with magnetic Fe@FeS@C nanoparticles (CFeS aerogels) were constructed from natural carrageenan. The unique redox potential of FeS, coupled with the barrier effect and the electron conduction property of the carbon layer, made the Fe@FeS@C nanoparticles exhibited the ultra-high ion selectivity. The resultant CFeS aerogels can selectively adsorb and reduce trace Au(III), Ag(I), and Pd(II) ions at ppb level in an aqueous solution with 29 coexisting cations. Even if the concentration of competing metal ions is 100-fold higher than those of the precious metal ions, the selectivity for Au(III), Ag(I), and Pd(II) ions remained above 99.2%. Moreover, the 3D carbon network immobilizing the Fe@FeS@C nanoparticles prevented the aggregation and detachment of the recycled precious metals, thereby enhancing the adsorption rate and capacity. CFeS aerogels rapidly achieved adsorption equilibrium for Au(III), Ag(I), and Pd(II) ions in 5-10 min, and have the saturated adsorption capacities of 321.2 mg·g
