Simultaneous analysis method of BTEX and TPH in soil
토양중 BTEX와 TPH의 동시분석법에 관한 연구
Abstract
A simple and rapid simultaneous analysis method of BTEX and TPH in soil was developed. 5g of soil sample were mixed with sodium sulfate and then extracted with 10 mL of mixture of acetone and dichloromethane (1:1). Extraction was performed for 10 min in sonicator and analysis was with GC-FID. The detection limits of BTEX and TPH was 0.8 and 10 mg/kg, respectively. The analytical recoveries were >90% for all BTEX and TPH. Low boiling point fuels and high boiling point fuels are consistently reproduced within RSD 7%. The analysis results show very simple and rapid quantitation of BTEX and TPH in soil sample with low RSD.
