Biodegradation of an explosive compound, glyceryl trinitrate (GTN), was studied with a denitrifying microbial culture grown in a sequencing batch reactor and a GTN acclimated denitrifying culture. The GTN acclimated culture, which were fed on GTN for 1 month, degraded GTN regioselectively via denitr...

glyceryl trinitrate(GTN)의 단점은 무엇인가? | GTN은 환경으로 배출되는 농도가 높지 않으나, 인체에 큰 위해를 줄 수 있는 물질이며, 국내 사격장 및 화약생산 및 처리시설의 폐수로 배출될 가능성이 높은 물질이다. 그러나 배출 농도에 대한 자료가 없고, 안전문제로 인해 고농도 GTN에 대한 생물학적 처리실험을 수행하지 못하였다. | |
Nitroglycerin은 무엇인가? | Nitroglycerin은(Fig. 1) glyceride에 3개의 질산기가 첨가된 강력한 화약물질로, 이탈리아 화학자 Asconio Sobrero가 처음 합성하였으며 화학식명은 glyceryl trinitrate(GTN)이다(Husserl, 2011). GTN의 LogKOW는 1. | |
혐기성 조건에서의 GTN 분해가 갖는 장점은 무엇인가? | 003)L/g-hr이었고, 이 값은 문헌상의 혐기성 조건에서의 GTN 분해율의 약 101배, 호기성 조건에서의 GTN 분해율의 10−1 배에 해당하였다. 호기성 조건에 비하여 분해속도는 느리지만, 폐수처리 탈질반응조 혹은 토양 근권에서 GTN과 질산성 질소를 동시에 제거함으로써, 하천 혹은 지하수로 유입되는 질산성 질소를 감소시킬 수 있는 장점이 있다. |
