金管富集-国产冷原子荧光光谱法测定空调颗粒物中的汞
摘  要  通过对国产原子荧光仪进样系统进行改造,采用在线热解样品金管富集冷原子荧光法测定空调颗粒物中的汞。试样热解温度为700~750OC,金管释放温度为5500C,试样载气流速为120 mL/min。方法检出限为1pg,汞含量在0~1.5ng范围内呈线性关系,测定标准偏差为2.23%。用国家土壤标准GBW07410中的汞验证了方法的准确性,并对某医院空调颗粒物中汞含量进行了分析。
关键词  冷原子荧光,空调,颗粒物,汞

Gold canal enrichment-homemade cold atomic fluorescence spectrometry determine mercury in air particulate matter
Abstract Though homemade atomic fluorescence spectrometry sampling system ameliorated, the mercury of air particulate matter were determined with the Gold canal-line pyrolysis sample enrichment cold atomic fluorescence . The temperature of Sample pyrolysis was 700℃~750℃, the release temperature of gold canal was 550℃,the flow rate of the sample carrier gas was 120 mL/min. The method detection limit was 1pg,the mercury content present linear relationship in the range of 0~1.5ng , the determination standard deviation was 2.23%.The accuracy of the method was verified by Hg of National Soil standard GBW07410 and the mercury content of a hospital in air particulate matter were analyzed.
Key words  cold atomic fluorescence, air conditioning, particulate matter, mercury.

Gold tube for enriching - the domestic cold atomic fluorescence spectrometry for testing mercury's quantity of particles in airconditioner

abstract:through improving the domestic atomic fluorescence spectrometer system,we pyrolysis sample by heating through the method of Gold tube for enriching - the domestic cold atomic fluorescence spectrometry for testing mercury's quantity of particulates in airconditioner. Sample pyrolysis temperature is 700-750OC,the releasing temperature for gold tube is 5500C,  speed of gas flow for carrying sample is 120 mL/min.The detection limit of method is 1pg, the content of mercury is in linear relationship  within the scope of 0 ~ 1.5 ng, standard deviation is 2.23%.Mercury's quantity of GBW07410 proved the accuracy of the method, and the particles in a hospital's airconditioner is analyzed for testing mercury's content.

Keywords cold atomic fluorescence, airconditioner, particle, mercury

Gold enrichment - domestic cold atomic fluorescence spectrometry air particulates mercury
Picking through on domestic atomic fluorescence spectrometer system, using online pyrolysis sample gold cold atomic fluorescence spectrometry enriched air particulates mercury. Sample pyrolysis temperature for the 700-750OC, gold 5500C temperature for release, sample carrier gas flow for 120 mL/min. Methods detection limit, mercury content for 1pg in 0 ~ 1.5 ng linear relationship within the scope, standard deviation is 2.23%. In countries GBW07410 standard of soil mercury proved the accuracy of the method, and the air particles in a hospital mercury content is analyzed.
