The two hydrophobically-rendered systems, PAC16@SPIONs and PAC10Ph@SPIONs, the positively charged PAC3Imi+@SPIONs as well as their orthogonal binary SAM adsorbent systems (all in reference to uncoated SPIONs) were applied to aqueous biphenyl and PCB solutions. The magnetically extracted biphenyl and PCB amounts at the fixed pollutant-SPION ratio are summarized in Figure . Firstly, the molecular SAMs enable efficient magnetic collection overall. The uncoated SPIONs (reference) peak at 0.80 ± 0.47 nmol removal for PCB 77 while only extracting 0.20 ± 0.11 nmol for biphenyl. On the other hand, PAC16@SPIONs is able to remove 3.00 ± 0.42 nmol of biphenyl up to 5.10 ± 0.17 nmol for PCB 14 with a strong drop in performance for PCB 77. While PAC10Ph@SPIONs behaves similarly, PAC3Imi+@SPIONs shows as low removal as uncoated SPIONs for biphenyl, however, the highest magnetic extraction performance at all for PCB 77 of 4.86 ± 0.91 nmol.
