摘      要：Titanium dioxide nanotubes(TNTs)were prepared and used as catalysts for degradation of humic acid by titanium dioxide nanotubes/UV/*** a view of kinetics,the effect of calcination temperature and the synergistic effect of photocatalysis and ozonation were *** influences of reaction temperature,original pH value,dosage of TNTs and dosage of ozone on the reaction kinetics were also investigated,and the reaction kinetics model was *** result showed that photocatalysis and ozonation had a good synergistic effect and the best reaction temperature of TNTs was 400℃.The TOC removal of humic acid followed zero-order *** the model,the best reaction kinetics k was obtained under the condition with original pH value of 7.35,TNTs dosage of 0.806 g·L-1 and ozone dosage of 0.49 g·*** was 0.8095 mg·L-1·min-1 when the reaction temperature was 25℃ while 0.8231 mg·L-1·min-1 at 30℃.The theoretical predictions were in good agreement with the experimental data.
