Magnetic porous reduced graphene oxide-based dispersive solid phase extraction for triclosan quantification in water.

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
The preparation of emerging adsorbents promoted the sustained development of solid-phase extraction (SPE). Herein, magnetic porous reduced graphene oxide (MPrGO) was prepared to be applied to dispersive magnetic solid phase extraction (d-MSPE) of triclosan (TCS) from environmental water samples. TCS exists widely in water and has an endocrine disrupting effect on aquatic animals. We report an optimized workflow before gas chromatography (GC) for d-MSPE with 5 mg of MPrGO, 20 s extraction time, 4.5 mL (1.5 mL each time for three times) of methanol-5% (v/v) ammonia as elution. Recoveries of 110.3%-122.0% and 94.6%-96.2% were obtained for TCS spiked in surface water and tap water by the d-MSPE method with the relative standard deviations (RSDs) of less than 5.0%, respectively. The method was successfully applied to quantify the occurrence of TCS in reclaimed water samples. The d-MSPE analytical method is an efficient, simple, low-cost, recyclable method for monitoring traces of TCS in different water samples.
