xylenes

基本解釋

Benzene,toluene,ethylbenzene and xylenes(BTEX) are components which are commonly found in crud oil,contaminated ground water and air.
單環(huán)芳烴苯、甲苯、乙苯和二甲苯(簡(jiǎn)稱BTEX)是石油的重要組分,也是環(huán)境中需要重點(diǎn)監(jiān)測(cè)的致癌污染物。
As examples, the fungus degrades benzene, toluene, ethylbenzene, and xylenes (the so-called BTEX compounds), chlorinated compounds such as 2,4,5trichloroe- thylene (TCE), and trichlorophenols.
例如,這種真菌降解苯、甲苯、乙苯、和二甲苯(所謂的BTEX化合物),氯化物如2,4,5一三氯乙烯,三氯苯酚。
Objective To establish a gas chromatographic method with carbon disulfide desorption for benzene,toluene and xylenes in time-weighted average(TWA)concentration in the workplace air.
目的建立工作場(chǎng)所空氣中苯系物的時(shí)間加權(quán)平均濃度(TWA)氣相色譜測(cè)定方法。
