Study on the Methods Of Adsorbent Enriching-SFE Desorbing and Off-line GC-MS-DS Determination of Trace Organic Pollutants from Coal Smoke
摘要:
The optimum conditions of supercritical fluid extraction(SFE)desorping the organic pollutants adsorbed and enriched by the adsorbent Porapak P and the effects of the conditions on the efficiencies of SFE desorping organic pollutants are studied emphatically.Different kinds of organic adsorbents and modifiers were tested.The recoveries of SFE are compared with Soxhlet extraction.The recoveries between 93.1% and 109.3% are obtained for 25 kinds of compounds at 35 MPa,100℃ and 9.0 ml SF-CO2,and their relative standard deviations(RSD)are in the range of 0.6-12.6 percent.
