Abstract

Limbah hasil peleburan aluminium dari Desa Segodopuro, Kecamatan Sumobito, Kabupaten Jombang mengandung beberapa oksida logam dengan komponen utama aluminium oksida dan seng oksida. Kadar aluminium yang cukup tinggi yakni 52,90% membuat limbah ini berpotensi dijadikan sebagai adsorben pada studi adsorpsi Remazol yellow. Adsorpsi zat warna sintetik Remazol yellow dilakukan dengan metode batch. Optimasi dilakukan pada variasi waktu kontak (10-70 menit), dosis adsorben (4-28 mg), konsentrasi awal (10-60 mg/L), dan pH (2-10). Larutan hasil adsorpsi diukur absorbansinya menggunakan spektrofotometer UV-Vis pada panjang gelombang 417 nm. Kondisi optimum adsorpsi zat warna sintetik Remazol yellow menggunakan adsorben limbah peleburan aluminium yaitu pada waktu kontak 40 menit, dosis adsorben 20 mg, konsentrasi awal 40 mg/L, dan pada pH 3 dengan %Removal sebesar 90,78%. ====================================================================================================== Aluminum smelting waste from the Segodopuro, Sumobito, Jombang contains several types of metal oxides. The major metal oxides were aluminum and zinc oxide. The aluminum content in the smelting waste was about 52.90%. Thus, this waste was very prospective to be applied as Remazol yellow adsorbent. The adsorption of Remazol yellow was carried out by batch method. The adsorption optimization was carried out at various contact time (10-70 minutes), adsorbent dosage (4-28 mg), initial concentration (10-60 mg/L), and pH (2-10). The adsorption filtrate solution was measured using a UV-Vis spectrophotometer at a wavelength of 417 nm. The optimum condition of Remazol yellow dye adsorption was occured at 40 minutes contact time, 20 mg adsorbent dosage, 40 mg/L initial concentration, and at pH 3 with %Removal of 90.78%.
