Abstract

Industrial development increases pollution in the environment, while the results of industrial waste disposal generally produce waste containing heavy metals, one of which is mercury (Hg). Eggshell is waste originating from households and the food industry which is made from eggs and has the potential as an adsorbent to absorb mercury ions (Hg2 +). In this study, egg shells were prepared with two treatments: egg shell adsorbent and with eggshells activated by 30% NaOH after heating in a furnace at 600 oC for 2 hours then mashed with a particle size of 200 mesh. The adsorbent is then used to absorb Hg2 + ions from the Hg (NO3) 2 compound. H2O as much as 0.01 ppm with the activated eggshell and eggshell adsorbent weight of 2 grams each, where the adsorption process is carried out with 2 contact times, namely 60 minutes and 120 minutes and tested with a Mercury Analyzer. The adsorption process obtained, the optimum at the contact time of 120 minutes and the eggshell adsorbent treatment with an average percentage of 93.931%.
