建立了一种利用固相萃取法对固体废物浸出液（ TCLP ）中二硝基苯进行萃取， DB －5石英毛细管柱（30 m ×0．25 mm ×0．25μm）进行分离，质谱检测器检测二硝基苯的方法。方法在0．0020～0．0200 mg／L之间线性关系良好，二硝基苯三种同分异构体的检出限均为0．5μg／L，模拟样品加标回收率为93％～96％，RSD≤2％；实际固体废物样品测定的加标回收率为95％～98％。
建立瞭一種利用固相萃取法對固體廢物浸齣液（ TCLP ）中二硝基苯進行萃取， DB －5石英毛細管柱（30 m ×0．25 mm ×0．25μm）進行分離，質譜檢測器檢測二硝基苯的方法。方法在0．0020～0．0200 mg／L之間線性關繫良好，二硝基苯三種同分異構體的檢齣限均為0．5μg／L，模擬樣品加標迴收率為93％～96％，RSD≤2％；實際固體廢物樣品測定的加標迴收率為95％～98％。
건립료일충이용고상췌취법대고체폐물침출액（ TCLP ）중이초기분진행췌취， DB －5석영모세관주（30 m ×0．25 mm ×0．25μm）진행분리，질보검측기검측이초기분적방법。방법재0．0020～0．0200 mg／L지간선성관계량호，이초기분삼충동분이구체적검출한균위0．5μg／L，모의양품가표회수솔위93％～96％，RSD≤2％；실제고체폐물양품측정적가표회수솔위95％～98％。
A method was established for the determination of dinitrobenzene in Toxicity Characteristic Leaching Procedure ( TCLP) of solid waste.The sample was extracted by SPE, separated by DB-5 quartz capillary column (30 m ×0.25 mm ×0.25μm), and detec-ted by mass spectrometer.The relevant analytical parameters were optimized.Good linear relationship was obtained in the range of 0.002 0 mg/L~0.020 0 mg/L.The detection limits of three dinitrobenzene isomers were all 0.5μg/L, and the recovery rates were between 93%~96%and RSD≤2%.For the determination of solid waste samples, the recovery rates were between 95%-98%.
