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,

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,
