Anthropogenic activity releases hazardous contaminants and pollutants that are not removed fully by water treatments. Among such pollutants, bisphenol-A (BPA) and bisphenol-S (BPS) are included in a series of Endocrine Disruptive Compounds, which may cause disruption due to hormone blockage or mimicking. Thus, even though those pollutants are not considered lethal, they are hazardous to health due to their similarity to 17β-estradiol, and they have been shown to cause developmental malformation in Zebrafish and breast and prostate tumors in rodents. Both BPA and BPS have been found in water sources at concentrations >30 μg L^–1 and since water treatment plants are ineffective at removing them, their concentration is constantly increasing. The purpose of the present study, using a collection of experiments performed by B.Sc. and M.Sc. students, was to apply clay-based materials to the removal of such health hazards from water. Specifically adapted modified clays as neutral organoclays can optimize the interaction between pollutants and the matrix to achieve efficient adsorption. Such an approach is very effective for relatively insoluble pollutants such as BPA, but less so for the more soluble BPS. On the other hand, BPS can be photodegraded catalytically using raw clay or TiO₂-impregnated clay. At low catalyst concentration, the modified clay was as effective as a commercial TiO₂ catalyst, whereas combining it with H₂O₂ yielded considerably better results. In summary, clay minerals offer solutions for the removal of health-hazardous pollutants from water, based on different procedures and mechanisms. The versality of clay minerals allows 'tailoring' specifically adapted materials that might improve their efficiency based on such very specific pollutant-matrix interactions.

人为活动释放有害污染物和水处理无法完全去除的污染物。在这些污染物中，双酚-A（BPA）和双酚-S（BPS）被包含在一系列内分泌干扰化合物中，它们可能因激素阻塞或模仿而造成干扰。因此，尽管这些污染物不被认为是致命的，但由于它们与 17β-雌二醇相似，它们对健康有害，并且它们已被证明会导致斑马鱼的发育畸形以及啮齿动物的乳房和前列腺肿瘤。BPA 和 BPS 均在水源中被发现，浓度 >30 μg L ^–1由于水处理厂无法有效去除它们，因此它们的浓度不断增加。本研究的目的是使用 B.Sc. 进行的一系列实验。和理学硕士 学生们，将应用粘土材料去除水中的这些健康危害。特别适合作为中性有机粘土的改性粘土可以优化污染物与基质之间的相互作用以实现有效吸附。这种方法对 BPA 等相对难溶的污染物非常有效，但对溶解性更强的 BPS 则效果较差。另一方面，BPS可以使用生粘土或TiO ₂浸渍粘土催化光降解。在低催化剂浓度下，改性粘土与商业 TiO _{2一样有效}催化剂，而将其与 H ₂ O ₂结合产生明显更好的结果。总之，粘土矿物根据不同的程序和机制为从水中去除对健康有害的污染物提供了解决方案。粘土矿物的多样性允许“定制”特别适应的材料，这些材料可能会基于这种非常具体的污染物-基质相互作用来提高它们的效率。
