PENURUNAN KADAR AMONIA DENGAN MENGGUNAKAN ARANG AKTIF AMPAS KOPI

Abstract

<p><em>Salah satu alternatif pengolahan </em><em>amonia</em><em> adalah dengan metode adsorpsi dengan menggunakan adsorben salah satunya adsorben arang aktif ampas kopi. Tujuan penelitian ini untuk menghasilkan adsorben ampas kopi untuk menurunkan kadar amonia yang mempunyai %yield sebesar 56%. Arang aktif dibuat dengan cara merendam ampas kopi dalam larutan HCl 0.1M selama 48jam. Karbon aktif dibakar dalam muffle furnance pada suhu 600°C. Karbon aktif diuji karakteristik yang terdiri dari uji kadar air, kadar abu, daya serap terhadap iodium dan lolos mesh. Waktu kontak dan berat adsorben ampas kopi yang optimal ditentukan untuk mendapatkan adsorbsi amonia dalam air limbah tahu. Variasi waktu kontak 30, 60, 90, 120 menit dan variasi berat adsoben 0.2, 0.4, 0.6, 0.8 gram. Dari hasil pengamatan, maka dapat disimpulkan bahwa kondisi optimum penurunan kadar amonia pada waktu 120 menit dengan berat adsorben sebanyak 0.8gram menghasilkan %yield sebesar 97.3%.</em><em></em></p>
