| Sumario: | The
photocatalytic degradation of the vapor odor of skim natural rubber latex,
which is composed of volatile organic compounds (VOCs-NR), was conducted using
iron-doped zinc oxide (Fe-ZnO) photocatalyst nanoparticles. The research
objectives were to study the photocatalyst, to develop the photocatalytic
reactor used for the photodegradation of VOCs-NR, and to analyze the odor
reduction of the degraded VOCs-NR. Fe-ZnO was prepared by the sol-gel method
and immobilized onto fiberglass cloth as the support material, followed by
annealing. The Fe-ZnO nanoparticles were dispersed on the fiberglass surface. A
photocatalytic reactor was developed for the gas phase. The research findings
showed that gas chromatography-mass spectroscopy detected 24 dominant chemical
components in the VOC-NR stock before photocatalytic degradation. The
components decreased to 11 after 30 min, only 3 components remained after 40
min of the photocatalytic process, and no component was observed after 80 min
of photoirradiation. An organoleptic test was conducted to validate that the
odor degraded to a very low level. |
