Abstract
In this study an environmentally-friendly, uncomplicated, and responsive method involving dispersive 
 liquid-liquid microextraction (DLLME) was presented for the isolation and analysis of 4-nonylphenol in 
 aquatic environments. The extraction process employed the undecanol–water dispersive liquid-liquid 
 system to isolate 4-nonylphenol. Essential variables impacting the efficiency of microextraction, such 
 as the quantities of 1-undecanol and acetonitrile, as well as the ionic strength of the aqueous solution, 
 were fine-tuned. Furthermore, the chromatographic parameters of the Gas Chromatography-Mass 
 Spectrometer (GC-MS) were optimized for precise analysis, and the analysis of 4-nonylphenol was 
 conducted using a linear calibration curve spanning 2-1000 µg/L, achieving a rapid 6-minute retention 
 time. The method exhibited a detection limit of 0.05 µg/L and a preconcentration factor of 188. Analyte 
 recovery rates ranged from 96% to 103%, having a relative standard deviation below 3%.The applied 
 procedure was effectively evaluated for its suitability in examining tap water and river water samples.
