This research was conducted with seven variations of contact time. The contact time used were one day, two days, three days, four days, five days, six days, and seven days. The data were analyzed by descriptive and statistic analysis. The One- Way Anova was used to determine the difference of efficiency of removal of Hg (II) ions in leachate using immobilized Skeletonema sp. based on contact time variation. The result showed that there was different among efficiency removal of Hg (II) ions in leachate using Skeletonema sp. immobilized based on contact time variation. The optimum value of removal efficiency of Hg (II) was 85,18% obtained at six days contact time. |
