摘要：

The photocatalytic activity of titanium dioxide prepared by a gamma-ray irradiation was investigated. The particles of the prepared TiO2 were very fine and had a narrow distribution. The particle size of the prepared TiO2 was in the range 20-100 nm and the average particle size was 61 nm from the particle size analyzer (PSA) result. The remaining ammonia gas after a UV irradiation was measured. Ammonia gas detection and analysis were carried out on a capillary column-gas chromatography (GC) system. The remaining ammonia gas of the prepared sample in a transparent tube after a UV irradiation was decreased owing to the neutralization reaction of the ammonium hydroxide and polyacrylic acid (PAC) and the photocatalytic activity of the nanosized TiO2 particles.
