“…The comparison also indicates that the proposed method presents the best sensitivity among the listed approaches except for SPE-HPLC/MS-MS method [31]. The recoveries obtained in the current method are better than that got in SPE-HPLC/MS-MS approach [31], and at the same level as that obtained in existing methods [11,29,30,[32][33][34][35][36][37]. The above comparison well implies that the established approach presents a good overall performance in the analysis of trace auxins.…”

“…As illustrated in Table 3, the extraction time spent in the current method is less than that needed in most of the previous studies [11, 30–32, 34, 35]. The established method consumes less solvent than that required in SPE‐HPLC/UV [30, 35, 36], SPE‐HPLC with MS‐MS [31], MSPE‐HPLC/UV [32], and liquid‐liquid‐liquid microextraction‐HPLC/MS [34].

Efficient enrichment is a challenging and indispensable step in the quantification of polar synthetic auxins in complex samples. In the current study, a new magnetic adsorbent based on polymeric ionic liquid/aminated carbon nanotube composite was fabricated with a one-pot precipitation copolymerization strategy and employed as the extraction phase of magnetic solid phase extraction of synthetic auxins. Various characterization techniques were utilized to inspect the morphology, structure, magnetic property, and functional groups of the prepared adsorbent. Under the optimal conditions, the obtained adsorbent displayed satisfactory capture performance towards studied auxins through multiple interactions. Adsorption studies evidenced that the adsorption procedure of the developed method towards analytes was fit for the Freundlich adsorption model and pseudo-second-order kinetics. Combining with high-performance liquid chromatography, sensitive and reliable method for the identification and quantification of trace synthetic auxins in environmental water and fruit juice samples was developed. The obtained limits of detection for water and fruit juice samples located in the ranges of 0.0059-0.013 and 0.018-0.031 μg/L, respectively. Recoveries in actual samples with different fortified contents varied from 82.2% to 117%, with satisfactory reproducibility. The results will evidence that the introduced extraction technique is a useful alternative for the entrapment of trace synthetic auxins from complex samples.
