Abstract

ZnO/rGO@UiO-66 telah berhasil disintesis dengan variasi penambahan massa ZnO/rGO 5, 10, 15, 30, dan 50% terhadap massa UiO-66 yang berturut-turut dinotasikan sebagai ZR5U, ZR10U, ZR15U, ZR30U, dan ZR50U. Sintesis UiO-66 dilakukan dengan memanfaatkan bahan alam pasir zirkon (PZ) sebagai prekursor ZrOCl2 penghasil Zr4+ dengan metode solvotermal dalam pelarut DMF pada suhu 120°C selama 24 jam. Modifikasi ZnO/rGO@UiO-66 dilakukan secara impregnasi. Difraktogram X-ray Diffraction (XRD) material hasil sintesis menunjukkan puncak karakteristik pada 2θ = 7,02° dan 8,14° yang sesuai dengan pola difraktogram UiO-66 standar. Spektra Fourier Transform Infrared (FTIR) material hasil sintesis menunjukkan pita serapan pada panjang gelombang yang sama dengan UiO-66 dan ZnO/rGO yang telah dilaporkan. Morfologi permukaan dari ZnO/rGO@UiO-66 berupa partikel bulat tidak beraturan yang terdispersi merata hampir sama dengan morfologi permukaan UiO-66. Hasil pengukuran dengan adsorpsi-desorpsi N2 menunjukkan bahwa SBET dari material UiO-66 dan ZR10U berturut-turut sebesar 458,756 m2/g dan 308,313 m2/g. Nilai celah pita dari komposit ZR10U sebesar 3,71 lebih rendah dari material UiO-66 sebesar 3,78. Hasil uji adsorpsi tetrasiklin menunjukkan bahwa ZR30U memiliki kapasitas adsorpsi tertinggi sebesar 114,639 mg/g serta mengikuti model kinetika orde dua semu. Hasil uji fotokatalitik menunjukkan bahwa ZR30U memiliki nilai persen degradasi sebesar 93% pada menit ke 120. Hal ini menunjukkan bahwa ZR30U berpotensi untuk diaplikasikan pada penghapusan antibiotik tetrasiklin dalam air yang lebih besar.

ZnO/rGO@UiO-66 has been successfully synthesized with variations in the addition of ZnO/rGO mass of 5, 10, 15, 30, and 50% to the mass of UiO-66, respectively denoted as ZR5U, ZR10U, ZR15U, ZR30U, and ZR50U. The synthesis of UiO-66 was carried out by utilizing natural zircon sand (PZ) as a precursor of ZrOCl2 producing Zr4+ with a solvothermal method in DMF solvent at 120°C for 24 hours. Modification of ZnO/rGO@UiO-66 was carried out by impregnation. The X-ray Diffraction (XRD) diffractogram of the synthesized material showed characteristic peaks at 2θ = 7.02° and 8.14° which correspond to the standard UiO-66 diffractogram pattern. The Fourier Transform Infrared (FTIR) spectra of the synthesized material showed absorption bands at the same wavelength as the reported UiO-66 and ZnO/rGO. The surface morphology of ZnO/rGO@UiO-66 was in the form of irregular spherical particles that were evenly dispersed, almost the same as the surface morphology of UiO-66. The results of N2 adsorption-desorption measurements showed that the SBET of UiO-66 and ZR10U materials were 458.756 m2/g and 308.313 m2/g, respectively. Band gap value of the ZR10U composite is 3,71 lower than that of the UiO-66 material of 3,78. The results of the tetracycline adsorption test show that ZR30U has the highest adsorption capacity of 114,639 mg/g and follows a pseudo-second-order kinetic model. The results of the photocatalytic test showed that ZR30U had a degradation percentage of 93% at 120 minutes. This indicates that ZR30U has the potential to be applied to the removal of tetracycline antibiotics in larger water.
