Preparation of Ionic Liquid-immobilized Expanded Perlite and Its Analytical Application

Abstract

The ultra-light weight ionic liquid immobilized expanded perlite (IL-EP) was synthesized and characterized by Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM). ionic liquid immobilized expanded perlite (IL-EP) as a novel adsorbent solid phase extraction (SPE) coupled with UV-visible absorption spectrometry for the determination of abiraterone acetate/abiraterone was established. The results were shown that the IL-EP could be conveniently separated The method was applied to analyzing abiraterone acetate/ abiraterone in tablet and serum samples with reasonable results.
