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
Fe 0 and MoS 2 can synergistically activate H 2 O 2 to generate free radicals for the removal of refractory organic compounds. This study aims to evaluate the Fe 0 -H 2 O 2 -MoS 2 process for the removal of refractory organic compounds from bio-treated landfill leachate (BTL) under continuous operation mode. The results show that the dosage of H 2 O 2, Fe 0 and MoS 2 all affect the removal effect of the Fe 0 -H 2 O 2 -MoS 2 process on refractory organics during continuous operation. The removal rates of total organic carbon, absorbance at 254 nm and chroma at an initial pH of 3, [H 2 O 2 ] of 5 mM, Fe 0 of 0.4 g/L, MoS 2 of 0.4 g/L and reaction time of 60 min were 65.83%, 85.11% and 93.14%, respectively. The Fe 0 -H 2 O 2 -MoS 2 process can not only effectively destroy the complex structure of refractory organic compounds in the BTL treatment but also reduce the biological toxicity of BTL to a certain extent. In addition, a high organic removal rate can still be maintained during the long-term dynamic reaction process. Therefore, the Fe 0 -H 2 O 2 -MoS 2 process has excellent performance in removing refractory organic compounds from BTL under continuous operation conditions.
