Abstract :
There is a great interest in developing rapid analytical methods and provide appropriate parameters
for quantitative analysis of compounds derived from refractory pollutants. Such methods are important for
routine quality control analysis of an effluent before being discharged into the environment. Therefore, a rapid
methodology for identification and quantification of some aliphatic acids is proposed. A method using High
Performance Liquid Chromatography (HPLC) analysis was established for the identification and quantification
of six aliphatic acids including: maleic, acetic, fumaric, malonic, succinic, and oxalic acid. Chromatographic
separation was performed by a reversed phase C18 column with a mobile phase consisting of methanol and
aqueous 0.1% phosphoric acid in a ratio (10:90) ) with a flow of 0.75 mL min-1 in isocratic mode.The
calibration curves showed excellent coefficients of determination (R2 e” 0.99) at the concentrations tested. The
recoveries were 54.72 to 99.70% for spiked samples. The method is appropriate for the detection of aliphatic
acids, which can be applied to monitor the effluent.
