Method for the determination of carboxylic acids in industrial effluents using dispersive liquid-liquid microextraction with injection port derivatization gas chromatography–mass spectrometry

Abstrakt

The paper presents a new method for the determination of 15 carboxylic acids in samples of postoxidative effluents from the production of petroleum bitumens using ion-pair dispersive liquid-liquid microextraction and gas chromatography coupled to mass spectrometry with injection port derivatization. Several parameters related to the extraction and derivatization efficiency were optimized. Under optimized experimental conditions,the obtained limit of detection and quantification ranged from 0.0069 to 1.12 ug/mL and 0.014 to 2.24 ug/mL, respectively. The precision (RSD ranged 1.29–6.42%) and recovery (69.43–125.79%) were satisfactory. Nine carboxylic acids at concentrations ranging from 0.10 ug/mL to 15.06 ug/mL were determined in the raw wastewater and in samples of effluents treated by various oxidation methods. The studies revealed a substantial increase of concentration of benzoic acids, in samples of wastewater after treatment, which confirms the need of carboxylic acids monitoring during industrial effluent treatment processes.
