| Outline of Final Research Achievements |
For improving the quality of recycled expanded polystyrene foam, some methods of reducing the odor within it were introduced and the odor reduction effect was evaluated. In the first step, near-infrared spectroscopy was used for detecting fish odor polluted foam and some useful wave lengths were nominated by spectra analysis. In the second step, dilute solution of hydrochloric acid was sprayed on the odor-polluted polystyrene foam. As the results, most of the odors intensity was weaken into the level of one-tenth of original one. In last step, the extract from ‘Amanatsu’ fruit showed the best odor masking performance among extract samples from seven fruit used.
