Abstract

HKUST-1 dan Fe3O4/HKUST-1 dengan penambahan massa Fe3O4 terhadap HKUST-1 sebesar 20% berhasil disintesis dengan metode solvotermal dalam campuran pelarut air:etanol:DMF dengan perbandingan 1:1:1 (v/v) pada suhu 100 ⁰C selama 10 jam. Material Kitosan/Fe3O4/HKUST-1 dengan variasi penambahan massa kitosan terhadap komposit Fe3O4/HKUST-1 sebesar 2,5; 5; dan 10% berhasil disintesis menggunakan metode impregnasi, yang berturut-turut dinotasikan sebagai Chi(2,5)/Fe3O4/HKUST-1, Chi(5)/Fe3O4/HKUST-1, dan Chi(10)/Fe3O4/HKUST-1. Pola difraktogram XRD menunjukkan puncak karakteristik yang sesuai dengan pola HKUST-1 standar. Spektra FTIR material hasil sintesis memiliki pita serapan pada bilangan gelombang yang sama dengan HKUST-1 yang telah dilaporkan. Morfologi Chi/Fe3O4/HKUST-1 berupa kristal oktahedral yang sesuai dengan morfologi HKUST-1. Hasil adsorpsi-desorpsi N2 menunjukkan SBET sebesar 676 m2/g untuk HKUST-1, 988 m2/g untuk Fe3O4/HKUST-1 dan 21 m2/g untuk Chi(10)/Fe3O4/HKUST-1. Hasil uji adsorpsi terhadap zat warna congo red menunjukkan bahwa Chi(10)/Fe3O4/HKUST-1 memiliki kapasitas adsorpsi tertinggi sebesar 193,26 mg/g serta mengikuti model kinetika orde dua semu dan isotermal adsorpsi Langmuir.
================================================================================================
HKUST-1 and Fe3O4/HKUST-1 with the addition of Fe3O4 mass to HKUST-1 of 20% were successfully synthesized by the solvothermal method in a mixture of water:ethanol:DMF solvent with a ratio of 1:1:1 (v/v) at 100 ⁰C for 10 hours.
Chitosan/Fe3O4/HKUST-1 material with variations in the addition of chitosan mass to the Fe3O4/HKUST-1 composite of 2.5; 5; and 10% were successfully synthesized using the impregnation method, which were denoted as Chi(2.5)/Fe3O4/HKUST-1, Chi(5)/Fe3O4/HKUST-1, and Chi(10)/Fe3O4/HKUST-1. The XRD diffractogram pattern gives rise to characteristic peaks that conform to the standard HKUST-1 pattern. The FTIR spectra of the synthesized material showed the same absorption band as HKUST-1 that has been reported. The morphology of Chi/Fe3O4/HKUST-1 is an octahedral crystal which corresponds to the morphology of HKUST-1. The results of the N2 adsorptiondesorption showed an SBET of 676 m2/g for HKUST-1, 988 m2/g for Fe3O4/HKUST-1 and 21 m2/g for Chi(10)/Fe3O4/HKUST-1. Congo red dye adsorption test results showed that Chi(10)/Fe3O4/HKUST-1 had the highest adsorption capacity of 193.26 mg/g and followed the second-order kinetics model and Langmuir adsorption isothermal
