Abstract: 본발명은 SPE형컬럼을이용한토양내 유류농도현장모니터링장치에관한것으로서, 토양이유류에오염되었는지유무를현장에서효과적으로분석하기위해토양내 유류를추출용매로추출하고, 추출된유류성분을근적외선분광광도계(NIR)를이용해분석함으로써, 유종의구분및 유류의오염농도를정확하게분석할수 있는것이며, 이에따라오염된토양의굴착시, 오염토와비오염토를현장에서명확하게구분할수 있음으로써토양정화기간및 정화비용을단축시킬수 있고, 궁극적으로는청정한국토환경관리및 오염된토양으로부터국민의위해성방지등에기여할수 있도록하는 SPE형컬럼을이용한토양내 유류농도현장모니터링장치에관한것이다.

Abstract: 본발명은토양이유류에오염되었는지유무를현장에서효과적으로분석하기위해토양내 유류를추출용매로추출한뒤, 추출된유류성분을근적외선분광광도계(NIR)를이용해분석함으로써, 유종의구분및 유류오염농도를정확하게분석할수 있는방법이다. 이는오염토양굴착시, 오염토와비오염토를명확하게현장에서구분할수 있음으로써, 토양정화기간, 토양정화비용을단축시킬수 있으며, 청정한국토환경관리및 오염된토양으로부터국민의위해성방지등에기여할수 있을것이라판단된다.
