Description
Summary:•Novel sodium 4-styrenesulfonate modified nanofibers mat (SS/PAN NFM) was prepared.•SS/PAN NFM was applied as adsorption medium of 96-well plate solid phase extraction.•The quantitative analysis of seven β-agonists residues in pork samples was achieved.•The established method was simpler, faster and lower-cost than the existing methods. In this work, sodium 4-styrenesulfonate functionalized polyacrylonitrile nanofibers mat (SS/PAN NFM) was firstly prepared and applied as 96-well plate solid–phase extraction adsorbent for quantitative determination of seven β-agonists residues in pork samples. The functional modification endowed the SS/PAN NFM with superior adsorption performance for target β-agonists. The adsorption process is spontaneous (ΔG
