Abstract

Smoke agents contained chlorinated compounds with a high environmental impact such carbon tetrachloride and hexachloroethane have been used for a long time by North Atlantic Treaty Organization (NATO).  The aim of this paper is to present an analytical method for the determination of these organochlorinated compounds based on Solid Phase Microextraction (SPME) and Gas Chromatography Mass Spectrometry (GC-MS) in optimizing the temperature and the time of fiber exposure. This method has been compared with the reference method based on static headspace coupled with GC-MS. The SPME method proves performance was improved especially in term of sensibility respect to the reference one. The SPME method has been successfully applied to real samples from a remediation soil of former military site.

 

Keywords: solid phase micro extraction, smoke agents, hexachloroethane, carbon tetrachloride

 

Abstrak

Agen asap yang diketahui mempunyai impak terhadap kesan alam sekitar mengandungi sebatian berklorin seperti karbon tetraklorida dan heksakloroetana telah diguna untuk tempoh masa yang lama oleh Pertubuhan Perjanjian Atlantik Utara (NATO). Kajian ini dilakukan bertujuan membangunkan satu kaedah analisis bagi penentuan kehadiran sebatian organoklorin berdasarkan teknik pengekstrakan mikro fasa pepejal (SPME) dan gas kromatografi- jisim spektrometri (GC-MS) bagi mengoptimumkan suhu dan masa pendedahan serat. Kaedah ini telah dibandingkan dengan kaedah rujukan berdasarkan ruang kepala statik yang dilengkapi dengan GC-MS. Kaedah SPME ini membuktikan prestasi yang lebih baik terutama dari segi kederiaan berbanding kaedah rujukan. Kaedah SPME telah berjaya digunakan untuk analisis sampel sebenar dari tapak tanah pemulihan kem tentera.

 

Kata kunci: pengekstrakan mikro fasa pepejal, agen asap, heksakloroetana, karbon tetraklorida
