Abstract

Mineral zirkonium dari pasir zirkon telah berhasil diekstraksi hingga kemurnian 85,18%. UiO-66 telah berhasil disintesis menggunakan hasil ekstraksi mineral zirkonium dari pasir zirkon. HKUST-1 dan komposit UiO-66/HKUST-1 telah berhasil disintesis menggunakan metode solvotermal dengan variasi penambahan massa UiO-66 sebesar 5%, 10% dan 15% terhadap massa HKUST-1 yang dinotasikan sebagai UiO-66(5)/HKUST-1 atau UH (5), UiO-66(10)/HKUST-1 atau UH (10) dan UiO-66(15)/HKUST-1 atau UH (15). Difraktogram material hasil sintesis menunjukkan puncak karakteristik yang sama dengan UiO-66 dan HKUST-1 standar yaitu pada 2θ = 7,3 dan 11,5. Spektra Fourier Transform Infrared (FTIR) material hasil sintesis menunjukkan pita serapan pada bilangan gelombang yang sama dengan UiO-66 dan HKUST-1 standar yaitu pada bilangan gelombang 670 cm-1 dan 731 cm-1. Morfologi komposit UiO-66/HKUST-1 berupa kristal oktahedral seperti HKUST-1 dengan permukaan ditutupi bulatan kecil bergerombol seperti UiO-66. Hasil adsorpsi-desorpsi N2 menunjukkan kurva isotermal tipe I dan IV untuk semua material hasil sintesis dengan SBET material UiO-66, HKUST-1, UiO-66(5)/HKUST-1 dan UiO-66(15)/HKUST-1 berturut-turut sebesar 406,9; 1108,14; 814,8; 728,6 m2/g. Hasil uji adsorpsi methylene blue menunjukkan bahwa komposit UiO-66(15)/HKUST-1 memiliki kapasitas adsorpsi maksimum tertinggi sebesar 238,1 mg/g dengan removal mencapai 81% dibandingkan UiO-66 (161,29 mg/g) dan HKUST-1 (200 mg/g). Mekanisme adsorpsi mengikuti model kinetika orde dua semu dan isotermal Langmuir.

Zirconium minerals from zircon sand have been successfully extracted with a purity of 85.18%. UiO-66 has been successfully synthesized using the extracted zirconium minerals from zircon sand. HKUST-1 and UiO-66/HKUST-1 composites have been successfully synthesized using a solvothermal method with varying amounts of UiO-66 at 5%, 10%, and 15% relative to HKUST-1, denoted as UiO-66(5)/HKUST-1 or UH(5), UiO-66(10)/HKUST-1 or UH(10), and UiO-66(15)/HKUST-1 or UH(15). The diffractogram of the synthesized material shows characteristic peaks identical to those of standard UiO-66 and HKUST-1 at 2θ = 7.3 and 11.5. The Fourier Transform Infrared (FTIR) spectrum of the synthesized material shows absorption bands at the same wavenumber as standard UiO-66 and HKUST-1 at wavenumbers 670 cm-1 and 731 cm-1 . The morphology of the UiO-66/HKUST-1 composite is an octahedral crystal similar to HKUST-1 with a surface covered with agglomerated small particles like UiO-66. The N2 adsorption-desorption results show isothermal curves of type I and IV for all synthesized materials, with a BET surface area of UiO-66, HKUST-1, UiO-66(5)/HKUST-1, and UiO66(15)/HKUST-1 in order of 406.9; 1108.14; 814.8; 728.6 m2 /g. The methylene blue adsorption test results show that the composite UiO-66(15)/HKUST-1 has the highest adsorption capacity of 238.1 mg/g with a removal rate of 81% compared to UiO-66 (161.29 mg/g) and HKUST-1 (200 mg/g). The adsorption mechanism follows a second-order kinetics model and Langmuir isothermal model.
