摘要: The present study is concern with the identification, characterization and activation of natural allophane as an adsorbent heavy metal ions Cr, Fe, Cd, Cu, Pb Mn. purposes this were to identify characterize Javanese volcanoes (Papandayan, Arjuna Wilis), determine optimum conditions adsorption isotherms that happened. identification was performed by using NaF, pH, FTIR, XRD. acidity analyzed ammonia adsorption. done in NaOH solution 1 N 3 N, soaking time 1, 3, 5 hours. according batch method variations contact 30, 60, 90 120 minutes. amount adsorbate. Atomic Absorption Spectroscopy (AAS) used analysis concentration solution. results show FTIR XRD indicate presence volcanic samples. Cr Cd are 3N for hours within minutes time, those Fe hour 30 Mn Cu 60 time. all kinds metals follow Freundlich equation which suggests physical interactions occur. Thus, can increase causing improve capacity about 50-100%..
