Objective:
To investigate the environmental degradation process of nonylphenol(NP):
Methods:
The NP was detected by HPLC, and the system of ultraviolet light, ferrous ion and hydrogen peroxide was used to promote photo-degradation of NP in water.
Results:
The maximal photo-degradation of NP occurred at the 5.0 mg/L of Fe2+, pH 2.5 and 1 ml/L of H2O2, the environmental factors in order of importance to promoting the photo-degradation of NP were: illumination time, initial concentration of NP, pH value, concentration of H2O2, concentration of Fe2+.
Conclusion:
The system of ultraviolet light, ferrous ion and hydrogen peroxide was effective in promoting the photo-degradation of NP.
