Abstract

HKUST-1 dan Ni-HKUST-1 dengan variasi doping Ni(II) sebesar 5, 10, dan 20% telah berhasil disintesis dengan metode solvotermal pada suhu 100 °C selama 10 jam dan berturut-turut dinotasikan sebagai HKUST-1, Ni(5)-H, Ni(10)-H, dan Ni(20)-H. Selain itu, dilakukan sintesis Ni-HKUST-1 dengan variasi doping Ni(II) yang sama dengan penambahan surfaktan CTABr dan dinotasikan sebagai H-CTAB, Ni(5)-H-CTAB, Ni(10)-H-CTAB, dan Ni(20)-H-CTAB. Pola difraksi material hasil sintesis menunjukkan puncak karakteristik yang sama dengan HKUST-1 standar. Analisa FTIR menunjukkan bahwa doping Ni(II) dan penambahan surfaktan tidak mempengaruhi gugus fungsi pada HKUST-1. Morfologi HKUST-1 berbentuk oktahedral. Doping Ni(II) dan penambahan surfaktan mempengaruhi keseragaman morfologi HKUST-1. Stabilitas termal material hasil sintesis antara 292-302 °C. Data isotermal adsorpsi-desorpsi menunjukkan luas permukaan spesifik HKUST-1, Ni(10)-H, Ni(20)-H, Ni(10)-CTAB, dan Ni(20)-CTAB berturut-turut sebesar 784,1 m2/g, 791,3 m2/g, 790,4 m2/g, 773,9 m2/g, dan 660,2 m2/g. Hasil adsorpsi pewarna Congo red dalam air menunjukkan bahwa material Ni(10)-H-CTAB memiliki kapasitas adsorpsi tertinggi, yaitu sebesar 445,618 mg/g serta mengikuti kinetika adsorpsi orde dua semu dan isotermal adsorpsi langmuir.
=======================================================================
HKUST-1 and Ni-HKUST-1 with Ni(II) doping variation, i.e. 5, 10, and 20% were successfully synthesized by solvothermal method at 100 °C for 10 hours and were denoted successively as HKUST-1, Ni(5)-H, N(10)-H, and Ni(20)-H. In addition, Ni-HKUST-1 was synthesized with same variation of Ni(II) doping with addition of CTABr surfactant and denoted as H-CTAB, Ni(5)-H-CTAB, Ni(10)-H-CTAB, Ni(20)-H-CTAB. The diffraction pattern of the sythesized solids showed the same characteristic peaks as the standard HKUST-1. FTIR analysis showed that doped Ni(II) and addition of surfactants didn’t affect the functional groups in HKUST-1. The morphology of HKUST-1 is an octahedral shape. Doped Ni(II) and addition of surfactant affected the morphological uniformity of HKUST-1. The thermal stability of the synthesized solids at temperature between 292-302 °C. Isothermal adsorption-desorption data showed specific surface area of HKUST-1, Ni(10)-H, Ni(20)-H, Ni(10)-H-CTAB, and Ni(20)-H-CTAB in the amount of 784,1 m2/g, 791,3 m2/g, 790,4 m2/g, 773,9 m2/g, dan 660,2 m2/g. The result of Congo red dye adsorption in water solution showed that Ni(10)-H-CTAB has the highest adsorption capacity (445,618 mg/g) and followed a kinetic adsorption model of pseudo second-order and isothermal langmuir adsorption.
