AB  - In order to study organophosphorus pesticides dissipation 
  rates under abiotic conditions, researchers showed laboratory observations on 
  the fenitrothion photodegradation and its temperature dependence. The kinetics 
  and thermodynamic of fenitrothion were studied at temperature range 20-50°C 
  under the irradiation of ultraviolet light. The results showed that photochemical 
  reaction of fenitrothion in organic solvents such as acetone under UV light 
  could be well described by the first kinetic equation and the photodegradation 
  efficiency increases with increasing temperature in the range 20-50°C. The 
  photodegradation rate constant of fenitrothion were 0.01, 0.03, 0.08 and 0.38 
  h<SUP>-1</SUP> and the corresponding half-lives were 31.6, 29.4, 9.6 and 7.8 
  h at 20, 30, 40, 50&deg;C, respectively. The apparent activation energy was 
  calculated to be 10.9 kJ mol<SUP>-1</SUP>. Thermodynamic parameters of activation 
  were also assessed for the degradation process.
