Study on the Photocatalytic Degradation of Ammonia Nitrogen in Aquaculture Wastewater by Sn4+-Doped Nano-TiO2 under UV Irradiation

Abstract:

The Sn4+-doped nano-TiO2 particles with various amounts of dopant Sn4+ irons was prepared by sol-gel method using tetrabutyl titanate(TEOT) as one of the primary raw materials at different calcination temperatures (400-700°C). The products were characterized by XRD and SEM, which revealed that the crystal structure of Sn4+-doped nano-TiO2 changes from anatase to rutile with the calcination temperature increasing, and the nanoparticles diameter was around 10-30 nm. The photocatalytic degradation of ammonia nitrogen in aquaculture wastewater was investigated by using Sn4+-doped nano-TiO2 under UV irradiation. The experimental results can be stated as follows: when the ratio of dopant Sn4+ was 3% wt, the calcination temperature of Sn4+-doped nano-TiO2 was 500 °C, the dosage of Sn4+-doped nano-TiO2 was 0.8 g/L, respectively, if the reaction time may last 4h, the removal rate of ammonia-N was expected to reach 87.13%.
