Abstract—Using semiconductor photocatalysis to anic
contamination has received great attention recently. In this II. MATERIALS AND METHODS
paper, study of using the anatasena nometer TiO2 light catalyzer
loaded on the fiberglass cloth to degrade the low concentration A. Reagent of experiment
organic phosphor pesticide dichlorovos (DDVP) in aqueous
Anatasena nometer TiO2 (purity>95%, particle diameter:
soultion was done. The results showed that the surface density of
30nm or so); concentrated sulfuric acid (heavy H2SO4),
TiO2 had great effect on the DDVP degradation. The best effect hydrochloric acid (HCl), sodium hydroxide (NaOH), hydroxide
of DDVP degration can be gotten when the surface density of
2 peroxide (H2O2) (the above levels were all .); DDVP
TiO2 loaded was (corresponding quality is ), and emulsifiable solution (80%), dimethoate emulsifiable solution
the degradation ratio was % on catalyzing reaction in 210
