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.

Conference Paper Description
The research on the determination of Cd(II) metal in river and seawater samples using the Adsortive Cathodic Stripping Voltammetry (AdCSV) method has been done. In order to increase the sensitivity and selectivity of Cd(II) measurement, it is necessary to determine the optimum condition for the variation of potential ligand accumulation, accumulation time, pH and optimum ligand concentration. It is also determined the accuracy and precision of the method used by determining the value of the relative standard deviation (SDR), as well as the recovery value. The result obtained is chalcone as the optimum ligand, the optimum accumulation potential is -0.1 V, the optimum accumulation time is 60 seconds, the optimum solution pH is 6, and the optimum chalcone concentration is 0.5 mM. The relative standard deviation value is 4.27%, the recovery value is 98.31%. The application of the VSAd method to water sample results the concentration of Cu(II) metal in the sample of Bangek river, Indonesia is 4.778 g/L and seawater in Teluk Kabung, Indonesia is 5.189 g/L.
