Mass Production and Outside Test of Microfluidic Paper Based Analysis Devices for Determining Chromium Ions in Industrial Wastewater.

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
Hexavalent chromium ions in industrial wastewater can bring serious pollution to the environment and a variety of harms to human health. It is necessary to develop a novel technique to determine the heavy ions. In this work, we designed a special machine to enhance the production of microfluidic paper based analysis devices (μPADs, ∼1000 μPADs/h), which could be used to determine the industrial wastewater. We optimized the diphenyl carbamide solution and the volume of liquid to be tested. Finally, we established a fitting curve of the standard Cr concentration and color intensity from the μPADs. We carried out outside experiments in an industrial park, which needed a great amount of stable and repeatable devices for the test. In the concentration range of 250-600 mg/L, 74% of the measurement results had a relative error of less than 20%; in the concentration range of 50-250 mg/L, 72% of the measurement results had a relative error of less than 20%. Our results demonstrated that the accuracy and repeatability satisfied the requirements for wastewater detection, which could be extended to industrial application.
