PENGARUH MASSA ADSORBEN BUAH JABON PUTIH (Anthocephalus cadamba) TERHADAP EFISIENSI ADSORPSI ION Hg2+

Abstract

The white fruit jabon (Anthocepalus Cadamba) can be used as an adsorbent because the chemical composition like cellulose and lignin that can absorb a big amount of an adsorbate. This research was aimed to test the adsorption ability of white jabon and to find out the adsorption optimum condition with varying the total number of adsorbent. Active charcoal created by the carbonization process at 300ᵒC for 30 minutes long, then the activation used NaOH and Charcoal with 1:3 (b/b) ratio. The optimization effect of adsorbent mass performed with adsorbent variant mass (0,25, 0,5, 0,75, and 1 g). This research showed that the optimum adsorbent mass happened at 0.75 g mass with 99.456% adsorption efficiency. Based on the result of statictic test showed Sig 0.163 (> 0.05), so can be included that there is no correlation between adsorbent mass variable and the adsorption efficiency
