 note = {神戸女学院内にある2ヶ所の水溜まりの水中の有機物量を COD 法により測定した。2010 年から2020 年にかけて有機物濃度は地点 A で 0.8-7.2 mg/L、地点 B で 5.5-57 mg/L で推移した。いずれの水溜まりも夏場に高く、冬場に低くなる傾向がみられた。水中の有機物を除去するために光触媒である二酸化チタンと酸化ジルコニウムを用いて検討した。はじめに、有機物としてグルコースを溶解した模擬環境水を用いて、太陽光と紫外線下で分解性をみると、二酸化チタンが酸化ジルコニウムに比べて分解能力が高いことがわかった。さらに、実環境水としてメダカが飼育されている水を用いて分解性をみると、模擬環境水と同様の傾向がみとめられた。このことから、有機汚濁の高い水を浄化するには、光触媒として二酸化チタンを用いることが有効であることがわかった。, The concentrations of organic matters in the water samples from two puddles at Kobe College were measured using the chemical oxygen demand (COD) method. COD values ranged from 0.8 to 7.2 mg / L and from 5.5 to 57 mg / L in samples from stations A and B, respectively between 2010 and 2021 and were high in the summer and low in the winter both stations. Photo catalysts titanium dioxide and zirconium oxide were used to remove organic matter from the water samples. The removal of organic matter in water samples in which glucose was dissolved as an organic substance, was examined under sunlight or ultraviolet rays. It was found that titanium dioxide had a higher ability to decompose organic matters than zirconium oxide. Furthermore, when we examined the removal of organic matters from the water samples in which medaka were bred, we found trends similar to those seen in water samples in which glucose was dissolved. These results indicate that titanium dioxide is effective for removing organic matters from water samples.},
