Abstract
|
In the study, urchin-like TiO2 microparticles have been synthesized by a simple
hydrothermal method for diazinon degradation. The as-prepared particles were characterized
by transmission electron microscopy (TEM) and scanning electron microscopy (SEM). The
urchin-like structure of TiO2 is revealed by TEM and SEM analysis. The degradation rate was
strongly influenced by the pH, catalyst dosage and diazinon concentration. The degree of
diazinon degradation was about 87% under UV irradiation after 3 h.
