Abstract
Sintesis UiO-66 modulator (UiO-66-M) dilakukan menggunakan metode solvotermal dengan rasio penambahan asam asetat 1 : 100 pada suhu 120°C selama 24 jam. UiO-66-M diimpregnasi dengan kitosan menggunakan variasi jumlah kitosan 2,5%; 5%; 10%; dan 20% dinotasikan sebagai CS(2,5)/UiO-66-M, CS(5)/UiO-66-M, CS(10)/UiO-66-M dan CS(20)/UiO-66-M. Komposit Kitosan/UiO-66-M dikarakterisasi menggunakan XRD, FTIR, SEM, TGA dan Adsorpsi desorpsi N2. Hasil karakterisasi XRD menunjukkan puncak karakteristik pada 2θ = 7,12 dan 8,41° sesuai dengan UiO-66 standar. Spektra FTIR menunjukkan pita serapan pada bilangan gelombang yang sesuai dengan kitosan/UiO-66 yang telah dilaporkan. Hasil SEM menunjukkan morfologi kitosan/UiO-66-M berbentuk oktahedral mirip dengan morfologi UiO-66-M. Hasil uji adsorpsi-desorpsi N2 menunjukkan SBET dari material UiO-66-M sebesar 1329,98 m2/g. Stabilitas termal dari UiO-66-M dan CS(10)/UiO-66-M mencapai suhu 410°C. Hasil uji adsorpsi MO menunjukkan bahwa CS(20)/UiO-66-M memiliki kapasitas adsorpsi maksimum sebesar 294,118 mg/g serta mengikuti model kinetika orde dua semu dan isotermal Langmuir.

Synthesis UiO-66 (UiO-66-M) modulator was performed using a solvothermal method with a ratio of acetic acid 1: 100 at 120 ° C for 24 hours. UiO-66-M was impregnated with chitosan using variations in the amount of chitosan 2.5%; 5%; 10%; and 20% are denoted as CS(2,5)/UiO-66-M, CS(5)/UiO-66-M, CS(10)/UiO-66-M and CS(20)/UiO-66-M . Chitosan/UiO-66-M composites were characterized using XRD, FTIR, SEM, TGA and N2 desorption adsorption. The XRD characterization results showed characteristic peaks at 2θ = 7.12 and 8.41° according to the UiO-66 standard. The FTIR spectra chose the absorption band at the wave number in accordance with the approved Chitosan/UiO-66. SEM results show that morphology of Chitosan/UiO-66-M is similar to octahedral with morphology of UiO-66-M. N2 adsorption-desorption test results showed SBET from UiO-66-M material was 1329.98 m2/g. The thermal stability of UiO-66-M and CS(10)/UiO-66-M reaches a temperature of 410 °C. The MO adsorption test results show that CS(20)/UiO-66-M has the highest adsorption capacity of 294,118 mg/g as well as taking a pseudo second-order kinetics model and the Langmuir isothermal.
