Abstract

Abstrak. Penelitian eksperimen ini merupakan penelitian lanjutan yang bertujuan untuk mengetahui efektivitas katalis Fe₂O₃ yang terimpregnasi ke dalam keramik berpori gelcasting pada proses fotodegradasi fenol. Keramik berpori disintesis dengan metode gelcasting menggunakan clay alam sebagai bahan dasar dan binder pati sagu sebesar 8% dengan karboksimetil selulosa (CMC) sebagai dispersan. Keramik berpori gelcasting selanjutnya diembankan katalis Fe₂O₃ metode adsorpsi yang kemudian disebut Fe₂O₃-keramik berpori. Material yang dihasilkan selanjutnya digunakan dalam proses degradasi fenol 10 ppm (pH 8) selama 60 menit. Pengukuran konsentrasi hasil degradasi fenol menggunakan Spektrofotometer UV-Vis pada panjang gelombang maksimum 270 nm. Efektivitas katalis Fe₂O₃ dalam mendegradasi fenol meningkat ketika diemban ke dalam keramik berpori. Fotodegradasi tertinggi terjadi pada penambahan Fe₂O₃-keramik berpori dan diiridiasi UV sebesar 58,01%.
