Publicación Corrigendum to “Occurrence of common plastic additives and contaminants in mussel samples: Validation of analytical method based on matrix solid-phase dispersion”(Springer, 2021) Cañadas, Raquel; Garrido Gamarro, Esther; Garcinuño Martínez, Rosa Mª; Paniagua González, Gema; Fernández Hernando, Pilar; https://orcid.org/0000-0002-2935-6655Publicación Development and Characterization of SBA-15 Imprinted Polymers for Spiramycin Analysis(MDPI, 2024) González Gómez, Lorena; Morante Zarcero, Sonia; Pérez Quintanilla, Damián; Paniagua González, Gema; Garcinuño Martínez, Rosa Mª; Fernández Hernando, Pilar; Sierra Alonso, Isabel; https://orcid.org/0000-0003-2377-8555; https://orcid.org/0000-0001-6448-2385; https://orcid.org/0000-0002-7150-122X; https://orcid.org/0000-0003-2091-6772This work focuses on the development of a hybrid material based on SBA-15 silica with a molecularly imprinted polymer (MIP), using spiramycin (SPI) as a template, for use as sorbent in solid-phase extraction (SPE). Characterization techniques such as nitrogen gas adsorption–desorption isotherms, infrared spectroscopy and scanning electron microscopy confirmed the structure and properties of the SBA-15@MIP-SPI material. SPE conditions using SBA-15@MIP-SPI as sorbent were optimized, which allowed us to demonstrate the high selectivity and adsorption capacity of SPI on the synthesized material. The best conditions were 50 mg of sorbent, loading with 1 mL of standard solution or sample of cow milk previously extracted in acetonitrile and eluting with 3 mL of methanol with 1% acetic acid. After the optimization process, the material demonstrated recovery percentages of 81 ± 3% in SPI standard solutions and showed its potential in cow milk samples (71 ± 6%). The novelty of the research consists of the combination of MIPs with SBA-15, which could offer important advantages in terms of specific surface area and porous structure, thus improving performance and reducing the amount of sorbent compared to other traditional methods.
