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.

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。
