Abstract
Ib txoj hauv kev los rho tawm PAHs los ntawm cov sediments yog ua los ntawm kev siv cov tshuaj aqueous uas muaj cov khoom sib xyaw ntawm cov kua ionic (IL)1-hexadecyl-3-methylmidazolium bromide(HDMIm-Br) raws li qhov nruab nrab rho tawm. Kev tsom mus rau microwave-pab extraction tau siv los txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau tshuaj Cov txheej txheem tau siv rau cov ntaub ntawv pov thawj siv sediment BCR-535 thiab marine sediments los ntawm Tenerife (Canary Islands) nrog cov txiaj ntsig tau zoo. Txoj kev ua kom zoo tau muab qhov nruab nrab qhov rov qab zoo ntawm 91.1% rau rau ntawm xya PAHs tau kawm, nrog cov qauv sib txawv ntawm cov txheeb ze qis dua 10.4%. Cov txheej txheem tag nrho yog tus cwj pwm rau kev nthuav tawm lub sij hawm rho tawm tsawg (6 min), qis qis ntawm cov sediment (0.1 g), tsawg npaum li cas ntawm IL (45 mM), thiab tsawg ntim ntawm aqueous extractant tov (9 mL). Kev siv me me ntawm ob qho tib si IL thiab aqueous extractant tov tso cai rau cov txheej txheem los txiav txim siab ib puag ncig.
Kev siv:
- Brominated 1-hexadecyl-3-methylimidazole yog dav siv nyob rau hauv catalysts, tshuaj tiv thaiv media, electrochemistry, biotechnology thiab lwm yam teb.
- Nws yog feem ntau siv los ua hnyav, extractant thiab catalyst cab kuj nyob rau hauv cov organic synthesis.
- Nrog nws qhov tsis tshua muaj vapor siab thiab zoo thermal stability, nws kuj tuaj yeem siv rau hauv qhov kub thiab txias molten ntsev systems thiab ionic kua roj teeb.
