The performance of simazine degradation using TiO2 nanotubes is strongly influenced by the morphology and structure of the nanotubes. TiO2 nanotubes were synthesized from pristine titanium foil in EG/NH4F/KOH solution using anodic oxidation technique. This study investigates the effect of fluoride concentration in the electrolytes on the efficiency of Simazine photodegradation. We found that the optimum NH4F concentration was 0.5 wt% resulted in 57.4% degradation rate of simazine after 240 min of UV illumination. The result was attributed to the well separated, ordered and uniform structure of TiO2 nanotubes. Having the optimum fluoride concentration in electrolyte is crucial as the photodegradation performance depends on the crystal structure, surface morphology, and phase stability of the TiO2 nanotubes.

通过优化TiO 2纳米管生长中的氟化物浓度,增强了Simazine除草剂降解

使用TiO 2纳米管降解simazine的性能受到纳米管的形态和结构的强烈影响。采用阳极氧化技术,在EG / NH 4 F / KOH溶液中由纯钛箔合成了TiO 2纳米管。这项研究调查了电解质中氟化物浓度对Simazine光降解效率的影响。我们发现,最佳的NH 4 F浓度为0.5 wt%导致在240分钟的紫外线照射下simazine的降解率为57.4%。结果归因于TiO 2的良好分离,有序和均匀的结构纳米管。在电解质中具有最佳的氟化物浓度至关重要,因为光降解性能取决于TiO 2纳米管的晶体结构,表面形态和相稳定性。
