Abstract

Penelitian penggunaan arang kulit pisang kepok (Musa normalis L.) teraktivasi NaOH sebagai adsorben ion logam Crom (VI)telah dilakukan. Sampel arang yang digunakan dalam penelitian ini diperoleh dengan cara pirolisis pada suhu 4000C dan waktu tinggal 2 jam. Parameter penelitian ini meliputi pengaruh pH terhadap kapasitas adsorpsi, waktu setimbang, dan kapasitas adsorpsi arang kulit pisang kepok. Hasil penelitian menunjukkan bahwa pada pH 2 diperoleh kapasitas adsorpsi optimum sebesar 0,8569 mg/g. Waktu setimbang adsorpsi arang kulit pisang kepok terjadi pada waktu 60 menit dengan kapasitas adsorpsi sebesar 3,2986 mg/g. Kapasitas adsorpsi arang kulitpisang kepok (Musa normalis L.) terhadap logam Cr6+ yaitu 0,8019 mg/g yang diperoleh pada waktu setimbang 60 menit dengan konsentrasi awal logam Cr6+ (isoterm adsorpsi) 75 ppm.
