description | In this study, a series of experiments were conducted using a standard solution containing ${\alpha}$ and ${\beta}$-endosulfan to follow the removal effect of residual pesticides on soil and aqueous solution. An analytical method for residual pesticides was established by a gas chromatography equipped Ultra II[$(30m{\times}0.25mm(ID){\times}0.25{\mu}m$] capillary column and a ${\mu}$-electron capture detector(${\mu}$-ECD). Recovery rates of residual pesticides for soil samples were 96-100%. The amount of ${\alpha}$ and ${\beta}$-endosulfan that was spread in the soil was checked for various period of time. It indicated that the amount was reduced to 73 and 61%, respectively. When the water spread amount increased from 10 to 100 mL, ${\alpha}$-endosulfan was eliminated from 45 to 85% and while ${\beta}$-endosulfan from 44 to 88%. Removal rates of ${\alpha}$-endosulfan and ${\beta}$-endosulfan were 99% and 98% respectively within 30 minutes. It was assumed that the organic salts and strong alkali elements contained in the pesticide degradator hydrolyzed the residual pesticide. 본 연구에서는 잔류농약을 효과적으로 제거하는 방법을 토양 및 수용액상에서 연구하였다. 이를 위해 표준물질은 유기염소계 ${\alpha}$-endosulfan, ${\beta}$-endosulfan을 사용하였다. 분석방법은 각각 채취한 시료를 전처리하여 Ultra II[$(30m{\times}0.25mm(ID){\times}0.25{\mu}m$] 컬럼을 장착한 GC-${\mu}$-electron capture detector(${\mu}$-ECD)로 분석하였다. 토양 중 잔류농약의 회수율은 96-100%로 나타났다. 토양에 농약분해제를 살포하여 시간별 ${\alpha}$-endosulfan, ${\beta}$-endosulfan의 변화량을 분석한 결과 73, 61% 감소하였다. 토양시료에 농약분해제를 첨가하고, 수분의 양을 10 mL에서 100 mL로 증가 시키면서, 잔류농약의 변화량을 측정하였다. 그 결과, ${\alpha}$-endosulfan은 45%에서 85 %로, ${\beta}$-endosulfan은 44%에서 88%로 제거되었다. 마지막으로, 수용액상에서도 시간별 endosulfan의 제거율 실험을 하였다. 실험 결과 30분 내에서 ${\alpha}$-endosulfan은 99%, ${\beta}$-endosulfan은 98%가 분해 제거되었다. 이와 같은 현상은 농약분해제에 많은 유기산염과 강알칼리 성분들이 알칼리 가수분해를 일으킨 것으로 추정할 수 있다. |
