摘要: Abstract A magnetic o-hydroxyazobenzene (M-HAzo) porous organic polymer was facilely prepared by a green azo coupling reaction in aqueous solution. The M-HAzo applied as new adsorbent for the first time to pre-concentrate phthalate esters (PAEs) from plastic bottled juice, followed their determination with high performance liquid chromatography-ultraviolet detection. effects of various parameters, i.e., mass ratio Fe3O4@SiO2 HAzo, extraction time, ionic strength, pH sample, desorption conditions were optimized. Under optimized conditions, based method exhibited good terms linear range (0.3–50.0 μg L−1), detection limit (0.08–0.50 μg L−1), accuracy (recovery 78.0–115.0%) and repeatability (relative standard deviation 2.9–7.8%). This work provides sensitive analysis PAEs at trace levels drinks, which is featured sensitivity, simple operation environmentally-friendly merit will have promising potential other pollutants.
