Determination of Volatile Organic Compounds in Petroleum Companies Using Liquid-Liquid Extraction

Abstract

The recovery study of volatile organic compounds from effluents of petroleum companies in Ilorin East Local Government Area and its effect on the environmental matrixsurface water, soil, sediment and plant were sampled. The liquid-liquid extraction procedure of two organic solvent (Hexane: Dichloromethane) (50 ml: 50ml) was employed to remove volatile organic compounds from matrix so as to obtain a good recovery and repeatability at 0.01μg/l, 0.02μg/l and 0.05μg/l respectively. Sediment, soil and leaf of plant samples (10 g) were dried and soaked in hexane prior to extraction procedures, after which it was totalled into a 2 ml vial for Gas chromatography analysis. At 0.05μg/l obtained a percentage mean recovery and relative standard deviation for effluent water (82.7±2.5 – 95.0 ±1.0 %), surface water (62.3±2.5 – 97.7±4.2 %), soil (72.7±2.1 – 96.3±3.8 %), sediment (85.7±3.2 – 91.7±2.5 % ) and plant (79.3±2.5 – 99.3±2.0 %). Correlation analysis was carried out to establish a relationship between effluent and other matrix, at 0.02 μg/l percentage mean recovery effluent has effect on the sediment at that concentration. The remaining concentration levels did not show any significant relationship with the effluent variables.
