Effective and reliable method for extractions of anthracene

Abstract

Anthracene often used as model compound for degradation study, especially for high molecular weight PAHs. Hence, efficient extraction of anthracene is vital forGC-MS analysis. This study focuses on the efficiency of extraction methods between Solid Phase Extraction (SPE) and liquid-liquid extraction (LLE). The study was also conducted to assess the effect of sonication during extraction process. LLE showed a higher recovery at 96.65% compared to SPE at 46.22%. For extraction method development in minimal salt solution,sonication prior to sample withdrawal showed the highest recovery at 94.25% compared to mechanical shaking at 73.67% and sonication extraction at 65.06%.Hence, this study exhibits a reliable and effective technique on anthracene extraction prior to GC-MS analysis. It is important for anthracene determination using GC-MS in further degradation study.
