چکیده مقاله:
Benzene has a carcinogenic effect on the human body and adsorption
from the air is the best way to control it. By this research, benzene
vapor was removed from the air based on a tantalum metal-organic
framework (Ta-MOF) by gas flow solid-phase interaction (GF-SPI).
Benzene adsorption with Ta-MOF was studied in the static and
dynamic systems at room temperature. The benzene concentration
was analyzed by gas chromatography equipped with an FID detector
(GC-FID). The factors affecting benzene removal efficiency like
initial concentration of benzene, amount of adsorbent, exposure time,
flow rate, and temperature were studied and optimized. The results
showed us, the adsorption capacities range of Ta-MOF for benzene
in the static and dynamic system were obtained between ۹۰-۱۶۰ mg
g-۱ and ۶۵-۱۳۵ mg g-۱, respectively. Also, the high removal efficiency
was achieved by more than ۹۵% at ۴۵°C, ۶۷.۵ mg L-۱ benzene
concentration, ۰.۵ g of Ta-MOF, and the flow rate of ۲۵۰ mL min-۱
for a dynamic system. By dynamic system, the benzene is generated
in the chamber, stored in a bag, and then moved on the surface of
Ta-MOF. The GF-SPI method was validated by GC-MS and spiking
real samples.
