Pada penelitian ini zeolit X berpendukung material serat berhasil disintesis menggunakan metode hidrotermal sederhana. Serat gelas glass wool digunakan sebagai material serat dengan variasi waktu dan konsentrasi pada aktivasi serat. Proses aktivasi serat gelas memberikan pengaruh terhadap kristalinitas zeolit X dan pertumbuhan kristal zeolit X pada permukaan serat. Hasil karakterisasi menggunakan XRD SEM AFM menunjukkan bahwa kristal zeolit X dapat tumbuh menyelimuti permukaan serat dengan kristalinitas paling tinggi pada konsentrasi aktivasi serat sebesar 4M selama 24 jam 1 hari. Luas permukaan dan karakteristik pori dianalisis menggunakan adsorpsi isotherm gas N2. Pengukuran adsorpsi karbon dioksida secara gravimetri menunjukkan bahwa zeolit X berpendukung material serat mampu menangkap gas karbon dioksida pada suhu ruang hingga mencapai 283 berat.
ABSTRACT
In this research zeolite X supported by fiber material was
successfully synthesized using a simple hydrothermal method.
Glass wool is used as fiber material with additional variation of
time and concentration at glass wool activation. Activation
process in glass wool has an effect toward crystallinity and
growth of zeolite X at fiber surface. The results of
characterization using XRD SEM and AFM showed that zeolite
X crystal grow at fiber surface with highest crystallinity while
concentration of activation reach 4M during 24 hours one day.
BET surface area and pore characteristic analyzed by N2
isothermal adsorption. Carbon dioxide adsorption measurement
by gravimetric method showed that zeolite X supported by fiber
material has capability to capture carbon dioxide at room
temperature until reach 283 wt..
