TiO thin films with mixtures of the anatase, rutile, and brookite phases were deposited on glass substrates via magnetron sputtering. Based on XRD and Raman results, the TiO-0.47 and TiO-3.47 films principally contained the brookite phase, while the TiO-1.27 and TiO-2.13 films were primarily anatase. The capacities of the TiO films to adsorb heavy metals were tested with Cr(VI) and Fe(III) solutions, and the maximum Cr(VI) and Fe(III) adsorption capacities were realized with the TiO-0.47 film (334.5 mg/g) and TiO-3.47 film (271.3 mg/g), respectively. SEM‒EDS results revealed the presence of Cr and Fe on the surfaces of the films, thus corroborating the ability of the TiO films to adsorb and remove heavy metals. They are strong candidates for use in wastewater treatment plants.
通过磁控溅射在玻璃基板上沉积了具有锐钛矿、金红石和板钛矿相混合物的TiO薄膜。基于X射线衍射（XRD）和拉曼光谱结果，TiO-0.47和TiO-3.47薄膜主要包含板钛矿相，而TiO-1.27和TiO-2.13薄膜主要是锐钛矿相。用Cr(VI)和Fe(III)溶液测试了TiO薄膜吸附重金属的能力，TiO-0.47薄膜（334.5 mg/g）和TiO-3.47薄膜（271.3 mg/g）分别实现了最大的Cr(VI)和Fe(III)吸附容量。扫描电子显微镜-能谱（SEM-EDS）结果表明薄膜表面存在Cr和Fe，从而证实了TiO薄膜吸附和去除重金属的能力。它们是用于污水处理厂的有力候选材料。
