Metric Options: Counts1 Year3 YearSelecting 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
Functionalized wood pulp (WP-g-GMA-d-GluN ) as biosorbent and dl-malic acid–hydrogen peroxide as leaching agent was used for the recovery of chromium [Cr(VI)] from e-waste (waste floppy disks) in this study. Presence of N-content in WP-g-GMA-d-GluN (8.013%), relative to pristine wood pulp, was achieved by C–H–N elemental analysis. Functionalized biosorbent was characterized through standard analytical tools (Fourier transform infrared spectroscopy, scanning electron microscopy, and thermo-gravimetric analysis). Cr(VI) concentration in leachate before and after uptake was measured by atomic absorption and UV–VIS spectrophotometer. Maximum Cr(VI) recovery from floppy disks was found to be 98.25%; 24.5625 mg g at room temperature for an initial Cr(VI) concentration of 25 mg l at pH 2.5. Organic acid regeneration was tried for several cycles with a view to recover the sorbed Cr(VI) and also to restore the biosorbent to its original state. The successful application of easily abundant wood pulp as a biosorbent has potential for a low technological pre-treatment step prior to economically not-viable, high-tech chemical treatments for the removal of Cr(VI) from e-waste.
