A convenient, rapid, and environmentally friendly method, emulsive liquid–liquid microextraction combined with high-performance liquid chromatography, was established to determine phthalic acid esters in tap, river, lake, sea water. After the method’s optimization, we obtained appropriate volume of extractant pure water, number strokes, separation methods, mass fraction demulsifier, demulsifier volume, sample salt amount, pH conditions. This method requires only 200 μL heptanoic (fatty acid) as 75 mg sodium acetate demulsifiers for fast separation, respectively, avoiding use further equipment. Emulsive offers substantial advantages over dispersive by eliminating need toxic dispersants, thereby preventing any influences dispersants on partition coefficients. The linear range detection ranged from 0.5 50 μg L−1, a limit 0.2 L−1 quantitation L−1. recoveries 80.2% 106.3%, relative standard deviations between 0.5% 6.7%. Five greenness metrics confirmed that this is aligns principles green analytical chemistry. proposed achieved score 8.42, surpassing other methods evaluated using SPMS. novel may well be valuable technique determining water samples.
