摘要: Abstract Functionalized metalloporphyrin [5,10,15,20-tetrakis-(4-carboxyphenyl)-porphyrin] was coupled with poly(amidoamine) (PAMAM) to form an adduct of iron porphyrin PAMAM dendrimer Mobil Composition Matter-41 (MCM-41) (FeP/Dend-MCM-41). MCM-41 used as a mesoporous nanomaterial support for FeP/Dend control pores adsorption. The materials obtained were characterized by X-ray diffraction, Fourier-transform infrared spectroscopy, diffuse-reflectance ultraviolet–visible 1H nuclear magnetic resonance, field-emission scanning electron microscopy, transmission and fluorescence spectroscopy. performance the synthesized FeP/Dend-MCM-41 adsorbent in solid-phase membrane tip extraction (SPMTE) evaluated N-nitrosodiphenylamine (NDPhA) nitrosamine from water samples prior high-performance liquid chromatography (HPLC). Under optimized conditions, method showed good linearity coefficients determination R2 > 0.995 concentration range 1–10,000 ng mL−1. offered limits detection (0.96 ng mL−1) quantification (3.21 ng mL−1) analyte recoveries 97–105% RSD
