Two different morphologies of FeTiO3 (nanopowders and nanosheets) were synthesized for the selective and efficient removal of Congo red and methylene blue dyes. The FeTiO3 samples were extensively performed by XRD, TEM, EDS, XPS, BET, UV-Vis, zeta potential, FTIR, and VSM analysis. The experimental data showed that FeTiO3 nanopowders (FTO-P) and FeTiO3 nanosheets (FTO-S) were mesoporous, and each had CR adsorption quantity of 110.68[Formula: see text]mg/g and 95.33[Formula: see text]mg/g, respectively. Although FTO-S had an excellent adsorption of 76.87[Formula: see text]mg/g for MB, FTO-P showed almost no MB adsorption. The studies indicated that adsorption conform to pseudo-second-order model. The electrostatic interactions and hydrogen bonding were deemed to the mainly adsorption mechanism. The magnetic properties of samples facilitated their recovery from solution after adsorption. The study shows that FeTiO3 was an excellent adsorbent due to its remarkable and selective adsorption performance and easy magnetic separation from aqueous solution.

具有磁恢复能力的纳米结构FeTiO3的制备、微观结构和染料吸附行为

FeTiO的两种不同形态3（纳米粉末和纳米片）被合成用于选择性和有效地去除刚果红和亚甲蓝染料。FeTiO3通过 XRD、TEM、EDS、XPS、BET、UV-Vis、zeta 电位、FTIR 和 VSM 分析对样品进行了广泛的分析。实验数据表明，FeTiO3纳米粉末 (FTO-P) 和 FeTiO3纳米片（FTO-S）是介孔的，CR吸附量分别为110.68[公式：见正文]mg/g和95.33[公式：见正文]mg/g。尽管 FTO-S 对 MB 有 76.87 [公式：见正文]mg/g 的出色吸附，但 FTO-P 几乎没有 MB 吸附。研究表明吸附符合准二级模型。静电相互作用和氢键被认为是主要的吸附机制。样品的磁性有助于它们在吸附后从溶液中恢复。研究表明，FeTiO3由于其显着的选择性吸附性能和易于从水溶液中磁分离，是一种优异的吸附剂。
