A study of bactericidal effect and optimization of pathogenic bacteria using TiO2 photocatalyst.

The photocatalytic degradation of Salmonella choleraesuis subsp. and Vibrio parahaemolyticus in water by TiO2 catalysts was investigated in a batch reactor. After 30 min of irradiation with UV light in the presence of 1 mg/ml of TiO2, death ratio of S.

Photocatalytic degradation of 2,4-dinitrophenol using TiO2 in aqueous solution.

A new method was developed to synthesize uniform anatase TiO2 nanocrystals by the hydrolysis of titanium tetraisopropoxide in nitric acid-isopropyl alcohol aqueous solutions at 353 K. The samples were characterized by XRD, TEM, FE-SEM, and specific surface area determination. In this work, the photocatalytic degradation of 2,4-dinitrophenol in the presence of TiO2 using ultraviolet (UV) light source was investigated in a batch reactor.

Bactericidal effect of TiO2 on the selected Vibrio parahaemolyticus and optimization using response surface methodology.

In this work, the bactericidal effect of TiO2 on selected typical food pathogenic bacteria, Vibrio parahaemolyticus was studied. V parahaemolyticus is an important pathogen of humans and aqua-cultured animals. We established the response surface methodology (Box-Behnken Design) to investigate the effect of principal parameters on the cell sterilization such as TiO2 concentration, UV illumination time, temperature, and pH.

Design of stormwater monitoring programs.

Stormwater runoff is now the leading source of water pollution in the United States, and stormwater monitoring programs have only recently been developed. This paper evaluates several stormwater monitoring programs to identify ways of increasing the likelihood of identification of high-risk dischargers and increasing data reliability for assisting in the development of total maximum daily loads. No relationship was found between various types of industrial activity or landuse and water quality data.

Characterization of PM2.5 aerosols dominated by local pollution and Asian dust observed at an urban site in Korea during aerosol characterization experiments (ACE)--Asia Project.

Daily fine particulate matter (PM2.5) samples were collected at Gwangju, Korea, during the Aerosol Characterization Experiments (ACE)-Asia Project to determine the chemical properties of PM2.5 originating from local pollution and Asian dust (AD) storms.
