Abstract
Treatment with aqueous sodium hydroxide solution plays an important role to impart certain desirable properties - feel and luster on the surface of polyester fiber. In this process alkali wastewater contains disodium terephthalate, ethylene glycol (EG) and residual sodium hydroxide. In this paper we report a new method containing the pretreatments of derivatization with benzoyl chloride and solvent extraction using pentane. The calibration curve of EG determined by GC/MS-SIM shows a good linearity in the range of 0.1 to <TEX>$25{\mu}g/mL$</TEX> having the standard deviation of <TEX>${\leq}8.7%$</TEX>. The recovery and the detection limit of this method are 91.9-93.7% and <TEX>$0.05{\mu}g/mL$</TEX> respectively.
