Abstract |
|
|
| The effect of gamma radiation on the degradation of phenol (hydroxybenzene), resorcinol (1,3-dihydroxybenzene) and hydroquinon (1,4-dihydroxybenzene) existing in wastewater was investigated. The effect of concentrations of these pollutants as well as the pH effect was studied. The results showed that phenol is highly resistant against the irradiation compared to other phenol compounds. Phenol was also a product of radiolysis of resorcinol and hydroquinon. On the other hand, the acid phase of the irradiated samples increased with the degradation rate of pollutants. Spectrophotometer (UV- VIS) and chromatography (HPLC) were used to monitor the promotion of the radiation products. The results illustrated the existing of many substances with organic alcohol, aldehide, ketone and acidic functional groups as a final radiation products. |
