Extraction of diclofenac by SiO2‐NH2@Fe3O4 and its determination: Central composite design

Abstract: In this work, magnetic nanoparticles (Fe3O4) were prepared by simple co‐precipitation method in aqueous medium and then subsequently modified with tetraethyl orthosilicate and 3‐aminopropyl triethylenesilane. The properties of the particles were characterized by FTIR spectroscopy X‐ray diffraction, transmission electron microscopy, and scanning electron microscopy. The SiO2‐NH2@Fe3O4 particles were successfully applied to simultaneously enrich and separate diclofenac from water, urine, and plasma samples. The … Show more

“…Several monitoring and optimization approaches have been used in extraction methods. Central composite design (CCD) is a versatile method that not only can investigate the effects of different factors on the extraction procedure concurrently but also can evaluate the interactions of parameters and, most importantly, predict actual optimum values of factors [19][20][21][22].…”
