Abstract

Penelitian ini bertujuan untuk mempelajari pemanfaatan bentonit aktif sebagai adsorben ion sianida (CN-). Bentonit diaktifkan dengan dua cara yaitu dengan pemanasan pada suhu 300°C dan dengan pengasaman menggunakan larutan HC1 0,01 N. Larutan CN- diinteraksikan dengan bentonit aktif pemanasan dan pengasaman dengan waktu pengadukan optimum adsorpsi 60 menit dan pH optimum 3. Filtrat diukur absorbansinya setelah direaksikan dengan larutan ammonium disulfida (NH4)2S2 dan larutan besi (III) menggunakan spektrofotometer UV-Vis. Dari hasil penelitian diperoleh nilai kapasitas adsorpsi untuk bentonit aktif pemanasan adalah 112,0667 mek/100 gram dan nilai kapasitas adsorpsi untuk bentonit aktif pengasaman adalah 127,5949 mek/100 gram. Translation: This research intended to study the using of activated bentonite as cyanide ion (CN-) adsorbent. Bentonite were activated by heating process at 300°C and add acid chloric 0,01 N. Cyanide solution was interacted with activated bentonite by using adsorption optimum time for 60 minutes and adsorption optimum pH of CN solution was 3. The absorbances were measured after reacting with ammonium disulfide (NH4)2S2 and iron (III) solution by using UV-Vis spektrometer at 459 nm. The data were used to make curves and to determine the value of adsorption capacity for heat activated bentonite and acid activated bentonite. The adsorption capacity for heat activated bentonite was 112,0667 mek/100 gram and the adsorption capacity for acid activated bentonite was 127,5949 mek/100 gram.
