摘要：

A technique for quantitative analysis of 3-aminopropylsilane on the surface of chemically modified Fe3O4 magnetic nanoparticles in the concentration range 0.32-3.03 mmol/g was developed using attenuated total reflection infrared spectroscopy. The technique was based on the ratios of band areas corresponding to Fe-O vibrations of the nanoparticles and Si-O vibrations of the coating as a function of the Si mass fraction in the nanocomposite that was determined by inductively coupled plasma atomic-emission spectroscopy.
