Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
In this work, a novel di-2-ethylhexylamine modified magnetic chitosan (FCS-DIOA) was successfully synthesized and used to recovery Re(VII) in Mo-Re binary mixtures. The percentage content and the chemical structure of adsorbent were characterized by elemental analysis, gas sorption, magnetic properties, X-ray diffraction analysis, infrared spectroscopy, and Boehm titration, respectively. We discussed the effects of steric hindrance and basic strength of the secondary, the tertiary ammonium, or the quaternary ammonium gel on rhenium adsorption selectivity and capacity. More important, Re-Mo binary component separations on the FCS-DIOA gel consistently showed that the kinetic separation method exhibited a greater sorption capacity and selectivity (Sel = 1.70-4.40). It was found that rhenium(VII) was adsorbed on the FCS-DIOA via charge-interactions and complexation by an infrared spectroscopy and X-ray photoelectron spectroscopy analysis. Relationships between adsorption mechanism and pH, adsorption isotherms, adsorption kinetics, adsorption thermodynamics, desorption, and regeneration were also discussed.
