Decomposition of Organophosphorous Compounds with Ultraviolet Energy(UV-C)

초록

두 종류의 유기인계 살충제인 디클로로보스와 클로로피리포스를 UV조사, UV 조사와 TiO₂ 분말 그리고 UV조사와 sea sand를 저압수은 램프를 이용하여 분해실험을 하였다 이 화합물의 확인은 가스크로마토그래프, 총유기탄소 그리고 이온크로마토그래프를 사용하였다. 두 물질 모두, UV조사와 sea sand가 UV 조사와 UV조사와 TiO₂분말보다 분해가 더 잘 되었다. 반응 최종생성물은 디클로르보스에서는 Cl^-, 클로로피리포스에서는 Cl^- SO₄^2-등이 생성되었다.

Two organophosphorous insecticides, Dichlorovos and Chloropyrifos were degraded in the presence of UV irradiation, UV irradiation with TiO₂ powder and UV irradiation with sea sand using low pressure mercury lamp. The identification of these compounds was carried out by gas chromatograph with a nitrogen-phosphorous detector, Total Organic Carbon and Ion Chromatograph, respectively. Both dichlorvos and chloropyrifos, UV irradiation with sea sand were more degradable than UV irradiation and UV irradiation with TiO₂ powder. The final products were Cl^- in Dichlorvos, C1^- SO₄^2- in Chloropyrifos, respectively.
