Abstract
INDONESIA:
Zeolit merupakan salah satu material alam yang dapat dimanfatkan sebagai penyaring molekular, penyerap bahan/adsorben, dan katalisator. Akan tetapi perlu adanya aktivasi untuk meningkatkan aktifitas dari zeolit alam. Zeolit alam diaktivasi menggunakan larutan NaCl 2 M dan kalsinasi pada suhu 450 ˚C selama 3 jam. Penelitian ini bertujuan untuk mengetahui perubahan karakter, luas permukaan dan kebasaan dari pengaruh variasi pengembanan KOH 10% dan 20% pada zeolit teraktivasi NaCl. Pengembanan KOH 10% dan 20% pada zeolit teraktivasi NaCl telah berhasil disintesis menggunkan metode sonikasi. Material hasil sintesis kemudian dikarakterisasi menggunakan instrumen X-ray Diffraction (XRD), adsorpsi-desorpsi N2, dan Temperature Progammed Desorption (CO2-TPD). Pengembanan KOH pada zeolit teraktivasi teridentifikasi adanya perubahan karakter dengan munculnya fasa KCl berdasarkan karakterisasi menggunakan XRD. Pengukuran luas permukaan menggunakan adsorpsi-desorpsi N2 didapatkan luas permukaan semakin turun berturut-turut sebesar 44,6 m2/g; 9,727 m2/g; 5,432 m2/g. Adanya penambahan KOH pada zeolit teraktivasi NaCl dapat menyebabkan penurunan nilai total kebasaan berdasarkan analisis menggunakan CO2-TPD.
ENGLISH:
Zeolite is one of the natural materials that can be utilized as a molecular filter, absorbent / adsorbent, and catalyst. However, there is a need for activation to increase the activity of natural zeolites. Natural zeolite was activated using 2 M NaCl solution and calcined at 450 ˚C for 3 hours. This study aims to determine the change in character, surface area and basicity of the influence of variations in KOH development of 10% and 20% on zeolite activated NaCl. The development of 10% and 20% KOH in NaCl-activated zeolite was successfully synthesized using the sonication method. The synthesized material is then characterized using the X-ray Diffraction (XRD) instrument, N2 adsorption, and Temperature Progammed Desorption (CO2-TPD). The development of KOH on activated zeolite was identified by character changes with the appearance of the KCl phase based on characterization using XRD. Measurement of surface area using N2 adsorption obtained surface area decreases by 44.6 m2/g; 9,727 m2/g; 5,432 m2/g. The addition of KOH in NaCl-activated zeolite can cause a decrease in the value of total alkalinity based on analysis using CO2-TPD.
