Selectively Adsorptive Extraction of Phenylarsonic Acids in Chicken Tissue by Carboxymethyl α-Cyclodextrin Immobilized Fe3O4 Magnetic Nanoparticles Followed Ultra Performance Liquid Chromatography Coupled Tandem Mass Spectrometry Detection
Figure 5
Effect of adsorption solvent on the adsorption efficiency of five phenylarsonic acids.
The concentration of each phenylarsonic acids was 50 ng/mL. Adsorption time was 30 min. 5 mg adsorbent was used. (n = 3, with RSD<4.5%).
