Abstract

Penghapusan zat warna metilen biru (MB) menjadi salah satu permasalahan lingkungan pencemaran air yang harus diatasi. Pada penelitian ini adsorben dan fotokatalis UiO-66-NH2; ZnO/UiO-66-NH2 dan GO@ZnO/UiO-66-NH2 disintesis dengan metode solvotermal pada suhu 120 °C selama 24 jam. Penambahan ZnO dilakukan secara insitu sebesar 8 dan 15% terhadap massa UiO-66-NH2, sedangkan penambahan grafena oksida (GO) dilakukan secara impregnasi pada variasi massa sebesar 20% terhadap massa total UiO-66-NH2 yang dinotasikan sebagai GO@ZnO(8)/UiO-66-NH2 dan GO@ZnO(15)/UiO-66-NH2. Material hasil sintesis dikarakterisasi dengan instrumen XRD, FTIR dan SEM-EDX. Pola difraktogram XRD pada semua hasil sintesis menunjukkan puncak karakteristik 2θ sekitar 7.24 dan 8.38° yang sesuai dengan UiO-66-NH2 referensi. Spektra FTIR hasil sintesis juga menunjukkan pita serapan pada bilangan gelombang yang sama dengan referensi. Material hasil sintesis diuji kinerjanya sebagai adsorben dan fotokatalis terhadap MB dalam air. Hasil uji adsorpsi terhadap menunjukkan kapasitas adsorpsi sebesar 41,25 mg/g dan persen penghapusan sebesar 83% pada waktu adsorpsi optimum 40 menit. Sedangkan hasil uji fotokatalitik terhadap MB menunjukkan kapasitas adsorpsi sebesar 48,10 mg/g dan persen penghapusan sebesar 96% pada menit ke 150 dengan material ZnO/UiO-66-NH2. Hal ini menunjukkan bahwa ZnO/UiO-66-NH2 berpotensi untuk diaplikasikan pada penghilangan zat warna MB dalam air.

The removal of methylene blue (MB) dye is one of the environmental problems of water pollution that must be overcome. In this study the adsorbent and photocatalyst UiO-66-NH2;
ZnO/UiO-66-NH2; and GO@ZnO/UiO-66-NH2 were synthesized by solvothermal method at 120 °C for 24 hours. The addition of ZnO was carried out in situ by 8 and 15% to the mass of UiO-66-NH2, while the addition of graphene oxide (GO) was carried out by impregnation at a mass variation of 20% to the total mass of UiO-66-NH2 which was denoted as GO@ZnO(8)/UiO-66-NH2 and GO@ZnO(15)/UiO-66-NH2. The synthesized material was characterized by XRD, FTIR, and SEM-EDX instruments. The XRD diffractogram pattern in all the synthesized results showed characteristic 2θ peaks around 7.24 and 8.38° which corresponded to the reference UiO-66-NH2. The synthesized FTIR spectra also showed absorption bands at the same wavenumber as the reference. The synthesized material was tested for its performance as an adsorbent and photocatalyst against MB in water. The adsorption test results on MB showed an adsorption capacity of 41.25 mg/g and a percent removal of 83% at the optimum adsorption time of 40 minutes. While the results of the photocatalytic test on MB showed an adsorption capacity of 48.10 mg/g and a percent removal of 96% at the 150th minute on ZnO/UiO-66-NH2 material. This indicates that ZnO/UiO-66-NH2 has the potential to be applied to the removal of MB dye in water.
