Penyisihan Ion Fe (II) dalam Air Sumur Bor dengan Metode Kolom Menggunakan Adsorben dari Ampas Tebu yang Diaktivasi secara Fisika dan Kimia

Halim Zaini, Cut Aja Rachmawati

Abstrak


Abstrak-Kualitas air untuk keperluan air bersih atau keperluan khusus harus memenuhi standar tertentu. Air yang belum memenuhi standar seperti air sumur  yang mengandung kadar logam tinggi seperti ion besi (II) belum layak konsumsi dan perlu dilakukan pengolahan. Salah satu tahap proses pengolahan air  untuk menurunkan kandungan mineral adalah metode adsorpsi. Penelitian ini bertujuan menurunkan kandungan besi (II) berdasarkan metode adsorpsi  sistem kolom, sebagai adsorben adalah ampas tebu. Variabel tetap terdiri dari masa adsorben 50 gr, volume adsorbat 10 liter, laju alir 7 liter/menit. Variabel bebas terdiri dari variasi waktu adsorpsi 0 30;60;90;120;150;180;210;240 menit dan kondisi adsorben: tanpa aktivasi, aktivasi fisik dan aktivasi kimia (H2SO4 0,5N dan NaOH 0,5N). Hasil penelitian menunjukan penyisihan besi(II)dipengaruhi oleh waktu kontak dan jenis  adsorben. Presentase penyisihan besi(II) tertinggi untuk masing-masing adsorben adalah adsorben tanpa aktivasi: 95,30%, adsorben dengan aktivasi fisika: 97,2%; aktivasi dengan H2SO4 0,5N: 98,3 % dan aktivasi dengan NaOH 0,5N: 90,6 %

Abstract- Water quality for clean water needs or special needs must meet certain standards. Water that has not met standards such as groundwater containing high metal content such as iron (II) ions is not yet suitable for consumption and needs processing. One stage of the water treatment process to reduce mineral content is the adsorption method. This study aims to reduce iron (II) content based on column system adsorption method, as an adsorbent is bagasse.  Fixed variable are adsorbent 50 g, adsorbat Volume 10 liters, flow rate of 4 liters / minute. Independence are variables consist of time-varying adsorption 0; 5;30; 60; 90; 120; 150; 180; 210; 240 minutes and adsorbent conditions: without activation, physical activation and chemical activation (H2SO4 0.5N and NaOH 0.5N). The results showed that iron (II) removal was influenced by contact time and type of adsorbent. The highest percentage of iron (II) removal for each adsorbent was adsorbent without activation: 95.3%, adsorbent with physical activation: 97.2%; activation with 0.5N H2SO4: 98.3% and activation with 0.5N NaOH: 90.6%
