本研究设计并制备了二乙烯三胺五乙酸修饰聚苯胺纳米纤维膜（DTPA-PANI NFsM）。通过PANI和DTPA的协同作用，DTPA-PANI NFsM对三类性质非常不同的抗生素表现出上级吸附性能：酚类、四环素类和磺胺类。DTPA-PANI NFsM的传质效率特别高。从等温线和热力学研究，有利的和自发的吸附过程被证实。通过FT-IR分析探讨了吸附机理。在优化条件下，建立了一种高效、快速、灵敏、经济的环境水体中抗生素残留的高通量检测方法。方法检出限低（酚类1.6-28.6 ng/L，四环素类10-34.3 ng/L，磺胺类0.46-15 ng/L），线性范围宽（1.5 ng/L-5 μg/L），回收率和精密度均令人满意。此外，DTPA-PANI NFsM具有良好的再生和重复使用性能，可重复使用至少12次。并通过实际样品的测试，验证了该方法在实际应用中的可行性.
In this study, novel diethylenetriaminepentaacetic acidmodified polyaniline nanofibers membrane (DTPA-PANI NFsM) was designed and fabricated. By the synergistic effect of PANI and DTPA, the DTPA-PANI NFsM demonstrated superior sorption performance towards three classes of antibiotics with very different properties: phenicols, tetracyclines and sulfonamides. The mass transfer efficiency of DTPA-PANI NFsM was particularly high. From the isotherm and thermodynamic studies, favorable and spontaneous adsorption processes were confirmed. The potential adsorption mechanisms were investigated by FT-IR analysis. Under the optimized conditions, an efficient, fast, sensitive and economical method for the high-throughput detection of antibiotic residues in environmental water was developed. Low detection limits (1.6–28.6 ng/L for phenicols, 10–34.3 ng/L for tetracyclines, 0.46–15 ng/L for sulfonamides), broad linear range (1.5 ng/L-5 µg/L) as well as satisfactory recoveries and precisions were obtained. In addition, DTPA-PANI NFsM exhibited excellent regeneration and reusability properties, which could be reused for at least 12 times. Also, the practical application feasibility of the method was confirmed by the test of actual samples.
