The chemicals called endocrine disrupters have been spread over the environment to influence the generative function of some species of living thing on the earth, and, therefore, the quick actions for this matter are required. The aim of this research is to find out the fundamental aspects on the adsorption-photodegradation system for diluted endocrine disrupters in water, and then to develop the system. In the first year, after establishing a simple estimation method for the activity of the system, we studied two systems for the degradation of dibutyl phthalate (DBF). One system was titania-pillared clay catalysts, and another was silica-supported titania catalysts. The results on the characterization of the catalysts and the activity for adsorption-photo-degradation clarified some aspects, e.g., (I) the adsorption amount influences on the photodegradation rate, (ii) the size and the crystallinity of the titania particle influence these activities, (iii) the hydrothermal treatment enhances the crystallinity of titania. (iv) our systems work under sunshine. In addition to them, in the second year, we investigated the influence of hydrophilicity/hydrophobicity of endocrine disrupters on the performance of the systems, and found that the enhanced crystallinity of titania by hydrothermal treatment were effective for each endocrine disruptors we examined.

称为内分泌剂的化学物质已经分布在环境上，以影响地球上某些生物的生成功能，因此需要快速行动。这项研究的目的是找出有关水中稀释的内分泌液，然后开发系统的吸附 - 降解系统的基本方面。在第一年，在建立了系统活性的简单估计方法之后，我们研究了两个用于苯基甲酸二丁酯（DBF）降解的系统。一个系统是钛岩石粘土催化剂，另一个是由二氧化硅支持的钛催化剂。有关催化剂表征和吸附 - 降解的活性的结果阐明了某些方面，例如（i）吸附量对光降解速率的影响，（ii）泰坦尼亚粒子的大小和结晶度影响着这些活动，（iii）水热治疗增强了水热治疗增强了泰坦的结晶性。 （iv）我们的系统在阳光下工作。除此之外，在第二年，我们调查了内分泌液的亲水性/疏水性对系统性能的影响，并发现通过热液治疗增强的二氧化钛的结晶度对我们检查的每种内分泌干扰物都是有效的。
