“…26,27 As a type of conducting polymer (CP), polypyrrole (PPy) possesses advantages of low toxicity, low cost, and ease of preparation. 28,29 PPy has been used to extract benzenoid organic compounds by strong p-p, hydrogen bonding interactions, and hydrophobic. 30,31 In SPE possess, PPy adsorbent usually needs to be separated from matrices by centrifugation or ltration, which reduce recovery.…”
