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
The present study deals with the successful utilization of bacterial biosorbent Arthrobacter sp. for the removal of Cd(II) ion from water in a batch and a continuous system. The maximum uptake capacity of free and immobilized biomass in batch system was 270.27 and 188.67 mg/g, respectively. The maximum removal percentage Cd of 88.9% was obtained at flow rate of 1.0 mL/min and 19 cm bed height in the column system. The bed depth service time (BDST) model was applied, which was found to be in good agreement with the experimental data with high correlation coefficient (>0.997) and low chi-square value (>1.62). Thomas and Yoon-Nelson models were also applied to the experimental data, and the Yoon-Nelson model provided a better description of experimental kinetic data in comparison to the Thomas model. Column regeneration studies were also carried out using 0.1 mol/L HCl as desorbent for seven sorption-desorption cycles. Furthermore, an attempt has been made to optimize the process conditions for the maximum removal using the central composite design, and the result predicted by optimization plots was 89.64%, which is close to the experimental data, that is, 88.9% at the same process conditions. © 2010 American Chemical Society.
