In this photocatalytic study, removal of bisphenol-A from aqueous solution was studied using the GF/Fe-TiO₂-CQD composite. Due to its health and environmental effects, this compound should be disposed of sources that are mainly industrial wastewater. The phis-chemical properties of the composite were determined by traditional analyzes of EF-SEM, EDX, BET, XRD, FTIR and DRS. In this study, different ratios of CQD in the composite (1.5, 4.5 and 7.5 wt%), pH, and bisphenol-A concentration as variable parameters were investigated. All analyzes, EF-SEM, EDX, BET, XRD, FTIR, show that the GF/Fe-TiO₂-CQD composite is well coated on glass fibers (GF) and all the elements in the catalyst are present. On the other hand, DRS analysis showed that CQD reduces the band gap of Fe-TiO₂ from 2.96 eV to 2.91 eV, it was 3.10 eV for TiO₂. Among different catalysts, GF/Fe-TiO₂-CQD_4.5wt% has the best performance. The results showed that for GF/Fe-TiO₂-CQD_4.5wt%, optimum for the process was at pH = 6 in low concentration of bisphenol-A. The first order model for the photocatalytic degradation process were well studied. In addition, GF/Fe-TiO₂-CQD_4.5wt% showed that it can be used many times with a minimal reduction in performance. As a result, the GF/Fe-TiO₂-CQD_4.5wt% composite can successfully remove bisphenol-A form in synthetic aqueous solution. However, it is necessary to further studies to applied that for real water source in water and wastewater treatment plants.

在这项光催化研究中，研究了使用 GF/Fe-TiO ₂ -CQD 复合材料从水溶液中去除双酚-A。由于其对健康和环境的影响，该化合物应从主要是工业废水的来源进行处理。复合材料的物理化学性质通过 EF-SEM、EDX、BET、XRD、FTIR 和 DRS 的传统分析确定。在本研究中，研究了复合材料中 CQD 的不同比例（1.5、4.5 和 7.5 wt%）、pH 值和双酚 A 浓度作为可变参数。所有分析（EF-SEM、EDX、BET、XRD、FTIR）均表明，GF/Fe-TiO ₂ -CQD 复合材料良好地涂覆在玻璃纤维（GF）上，并且催化剂中的所有元素均存在。另一方面，DRS分析表明CQD将Fe-TiO ₂的带隙从2.96 eV降低至2.91 eV，而TiO _{2 的}带隙为3.10 eV。在不同的催化剂中，GF/Fe-TiO ₂ -CQD _4.5wt%的性能最好。结果表明，对于GF/Fe-TiO ₂ -CQD _4.5wt%来说，最佳工艺条件是pH = 6、低浓度双酚A。光催化降解过程的一阶模型得到了很好的研究。此外，GF/Fe-TiO ₂ -CQD _4.5wt%表明它可以多次使用而性能下降最小。结果，GF/Fe-TiO ₂ -CQD _4.5wt%复合材料可以成功去除合成水溶液中的双酚A形式。然而，将其应用于水和废水处理厂的实际水源还需要进一步研究。
