气相色谱法测定空气和废气中联苯-联苯醚
Determination of diphenyl & diphenyl ether in air and waste-air by gas chromatography
【摘要】 研究了气相色谱法测定环境空气和废气中的联苯 -联苯醚。气体样品由中性氧化铝吸收 ,二硫化碳洗脱 ,FID检测。方法有较好的精密度 (变异系数 :联苯 1 2 .4% ,联苯醚 1 0 .6% ;回收率 :联苯 86.6%~ 1 0 0 % ,联苯醚 88.6%~95 .7% )和低的检出浓度 (联苯 0 .0 5 6mg/m3,联苯醚 0 .0 44 mg/m3) ;方法具有简便、快速、准确的特点。
【Abstract】 In the paper,the determination of Diphenyl & Diphenyl ether in air and waste air is studied by gas chromatography The gas sample is absorbed by Aluminum Oxide,CS 2 is used for eluate, determinating by FID The method has good precision(CV are:diphenyl 12 4%,diphenyl ether 10 6%;recoveries are:diphenyl 86 6%~100%,diphenyl ether 88 6%~95 7%) Low limit(diphenyl 0 056mg/m 3,diphenyl ether 0 044mg/m 3) The method has many advantage: simple,quick & exact
