Highly selective detection of Cr(VI) in water matrix by a simple 1,8-naphthalimide-based turn-on fluorescent sensor.
Article in Journal of fluorescence, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
4-Bis-(2-hydroxyethyl)amino-N-n-butyl-1,8-naphthalimide was developed into a turn-on fluorescent sensor for Cr(VI). In the mixture of N,N-dimethylformamide and deionized water (1:9, v/v), the sensor could highly selectively distinguish CrO4(2-) from Cr(3+), Na(+), K(+), Mg(2+), Ca(2+), Mn(2+), Fe(2+), Fe(3+), Co(2+), Ni(2+), Cu(2+), Zn(2+), Cd(2+), Hg(2+), Pb(2+), NO(3-), SO4(2-), PO4(3-), IO3(-), ClO(-) and Cl(-) by a 6-fold fluorescence enhancement. The working concentration of CrO4(2-) was from 0 to 90 μM with a detection limit of 3.6 × 10(-7) mol/L. The detection could be carried out in water matrix and within a wide pH range (approximately from 2 to 12), and a large number of environmentally and biologically relevant ions including Cr(3+) showed no significant interferences with the detection. The sensing mechanism was explored by reversibility and LC/MS analysis, as well as Job's plot experiment, and the results suggested that the recognition was based on the oxidation of the primary alcohol in the structure of the sensor by the Cr(VI) sources.
