Abstract

Kajian ini membahas proses pemisahan logam besi dalam sampel air secara adsorpsi. Secara umum bertujuan untuk melihat pengaruh perlakukan zeolit alam terhadap efisiensi penyisihan logam besi dalam sampel air baku. Proses adsorpsi menggunakan zeolit alam Banda Aceh dengan variasi ukuran partikel 40, 60, 80, dan 100 mesh. Kadar besi (Fe) dalam larutan sampel buatan adalah 1,25 mg/l agar mendekati kadar logam besi sesungguhnya. Kadar sampel asli air tanah dari Desa Alue Peunyareng Kabupaten Aceh Barat sebesar 1,1206 mg/l. Analisis kadar logam besi dilakukan dengan alat spektrofotometer. Hasil penelitian menunjukkan bahwa kemampuan adsorpsi maksimum diperoleh pada penyerapan dengan zeolit alam berukuran 100 mesh baik untuk sampel asli maupun sampel buatan. Aktivasi zeolit alam menaikkan kemampuan adsorpsi bahan penyerap hingga 154,72%. Kemampuan penyerapan yang dimiliki zeolit alam menurun hingga 92,25% manakala sampel yang diserap berupa air tanah karena sampel masih banyak mengandung bahan pengotor.

Abstract

Application of membrane technology for separation processes has been an efficient optional to produce a high quality of separation product. This process has been widely using in many field of industry. Therefore, knowledge of this membrane preparation is important for controlling the pore size of resulted membrane. This paper explained the basic concept of membrane preparation via non-solvent induced phase separation (NIPS) process by immersion precipitation. The effect of concentration of polyethersufone on the formation of cloud point of dope solution in N-methylpirrolidone was investigated. Two kinds of non-solvent as water and ethanol were used in order to study phase separation mechanism of polymer solution. Base on the amount of non-solvent of water and ethanol needed for cloud point formation, the ternary phase diagram can be performed. The experimental result indicated constant concentration of polyethersulfone, amount of ethanol needed was higher than water to obtain cloud point formation of polymer solution.Keywords: cloud point of polymer solution, immersion precipitation, membrane preparation
