Waterborne diseases produced by organisms of public health concern are prevalent worldwide, continuing to cause deaths annually. Conventional disinfectants (ozone, UV radiation, chlorine) have been insufficient in providing safe water as many studies revealed. TiO₂ is an attractive alternative to conventional methods because of its versatility and recently explored biocidal capacity due to advanced oxidation processes. The oligodynamic effect that TiO₂ seems to have on some microorganisms consists of effective lipid hyper oxidation of microorganism membranes, as well as protein interactions that lead to the alteration of the internal conditions and the inhibition of metabolic processes that eventually lead to their lysis. Nevertheless, a satisfactory description of other organisms is necessary to complete the disinfectant–organism interaction, and then the subsequent evaluation parameters of sanitation should proceed. In addition, solutions for feasibility, standardization of results for achieving consistent results and defined applications, lower costs, scalability, and security after its application need to be studied. Understanding its usage implies knowing the actual state of the art and its limitations for water disinfection purposes, as well as the potential benefits that overcoming such limitations would provide, thus allowing the possibility of establishing it as a feasible and popular technology.

TiO2 在水卫生应用中作为消毒剂的用途

由引起公共卫生关注的生物体产生的水传播疾病在世界范围内普遍存在，每年继续导致死亡。许多研究表明，传统消毒剂（臭氧、紫外线辐射、氯）不足以提供安全用水。TiO ₂是传统方法的一种有吸引力的替代方法，因为它具有多功能性，并且最近由于高级氧化过程而探索了杀生物能力。TiO ₂的微动力效应似乎对某些微生物的影响包括微生物膜的有效脂质过度氧化，以及导致内部条件改变的蛋白质相互作用和最终导致其裂解的代谢过程的抑制。尽管如此，对其他生物体的令人满意的描述是完成消毒剂-生物体相互作用所必需的，然后应继续进行后续的卫生评估参数。此外，需要研究可行性的解决方案，实现一致结果和定义应用程序的标准化结果，降低成本，可扩展性和应用后的安全性。了解其用法意味着了解现有技术及其在水消毒方面的局限性，
