| Abstract: | The photodegradation of p-nitrobenzoic acid was studied by using aluminum nitrate as photooxidant under UV light irradiation. The effects of dosage of NO-3, initial pH value and concentration of simulated wastewater, illumination time as well as dissolved oxygen on photodegradation of PNB were investigated. The results showed that NO-3 exhibited excellent photooxidation activity for the degradation of PNB. After 4 h UV irradiation, 90.8% of PNB photooxidation efficiency was achieved by NO-3 under the optimum treatment conditions. The property that cost-effective nitrate can play a significant role for the photodegradation of organic componds has actual meanings for organic wastewater treatment using photooxidation and photocatalysis technology. |
