Abstrak

Pemanfaatan batu apung sebagai adsorben telah diuji dalam aplikasi kolom adsorpsi dalam menyisihkan logam kromium (Cr) dari air tanah. Batu apung diambil dari pinggiran Sungai Pasak, Pariaman, Sumatra Barat. Kolom yang digunakan terbuat dari kaca dengan tinggi 130 cm dan diameter 2,6 cm. Percobaan dilakukan dengan menvariasikan ketinggian bed yaitu 65, 75 dan 85 cm dan kecepatan alir influen yaitu 2, 3 dan 4 gpm/ft², sementara konsentrasi influen yang digunakan sesuai kondisi sampel air tanah. Konsentrasi logam Cr dianalisis menggunakan inductively coupled plasma emission (ICPE). Kinerja kolom adsorpsi dapat dilihat dari kurva breakthrough yang merupakan plot antara rasio C_t/C₀ terhadap waktu pengambilan sampel. Hasil percobaan menunjukkan bahwa kondisi optimum dengan efisiensi penyisihan tertinggi yaitu 65,15% dan kapasitas adsorpsi sebesar 0,0031 mg/g diperoleh pada ketinggian bed 85 cm dan kecepatan alir influen 2 gpm/ft². Berdasarkan hasil percobaan disimpulkan bahwa semakin kecil kecepatan alir influen dan semakin tinggi bed adsorben maka efisiensi penyisihan logam terlarut meningkat. Kolom adsorpsi dengan batu apung Sungai Pasak Pariaman sebagai adsorben berpotensi untuk diaplikasikan dalam penyisihan logam Cr dari air tanah.
