    ANALISIS PARAMETER ADSORPSI PADA PROSES PENJERAPAN BESI DALAM AIR GAMBUT OLEH ARANG CANGKANG BIJI KETAPANG
    (2020-11) Putri, Desri Wahyu Riska; Muhdarina, Muhdarina
    Peat water contains iron (Fe) which causes the water to turn brownish red. In this research, the iron uptake was carried out using an adsorbent based on ketapang seed shells. The adsorbent was made by carbonization at 5000C for 30 minutes to obtain ketapang seed shell charcoal. Ketapang seed shell charcoal was applied to adsorb iron cations in peat water by analyzing the parameters of contact time, adsorbent weight and volume of peat water. The optimum conditions for the uptake of iron cations in peat water were 30 minutes of contact time, 1 g of adsorbent weight and 100 mL peat water volume to adsorbed iron weight per g of adsorbent 0.21x10-3 mg g-1 or the ad sorption efficiency of 38.07%.
