Abstract

In our study, ammoniated hollow mesoporous silica nanoparticles (NH₂-HMSN) with uniform diameter and stable structure were successively prepared via SiO₂ core hard template method. Fourier transformed infrared spectroscopy revealed that amino group was effectively modified. Adsorption experiments showed that adsorption capacity of NH₂-HMSN towards free fatty acids (FFAs) was superior to aminated mesopores or silica microspheres. Following through optimization of extraction conditions, FFAs from edible oil samples were successfully gathered by NH₂-HMSN and showed favorable linearities (0.2-90 μg g^-1), remarkably low limit of detections (0.03-0.15 nmol g^-1), acceptable recoveries (85.08-96.82 %) and relatively accurate precisions (1.64-4.99 %). In comparison to existing adsorbent, NH₂-HMSN could be successfully prepared via the chemical reaction of common raw materials under normal pressure and temperature. Furthermore, NH₂-HMSN with hollow and mesoporous structure was more effective than the current adsorbents aimed at FFAs analysis in aspect of surface area and adsorption capacity.
