PAC3Imi+@SPIONs extracts a sum of 7.98 ± 1.13 nmol of pollutants with the highest share of 42.9 ± 6.4 % coming from PCB 77, 34.5 ± 7.8 % from PCB 14, 12.5 ± 6.3 % from biphenyl and 10.0 ± 2.0 % from PCB 2. Again, PAC16@SPIONs and PAC10Ph@SPIONs behave similarly by extracting 16.55 ± 1.71 and 15.69 ± 1.45 nmol respectively with highest share stemming from PCB 14 (about 33 % in both cases) and no significant deviation between the shares of biphenyl, PCB 2 and PCB 77 (about 21-23 % each). In general, multiplicates show relatively large variations for PCB 14. With the binary coated PAC3Imi+/PAC16@SPIONs and PAC3Imi+/PAC10Ph@SPIONs overall 14.62 ± 1.65 and 13.34 ± 1.55 nmol of pollutants are removed. Here, PCB 14 also makes the biggest share of about 37 % in both cases, while the share of PCB 77 is estimated to 26.5 ± 3.2 and 28.5 ± 5.0 % respectively. The shares of biphenyl removed by PAC3Imi+/PAC16@SPIONs and PAC3Imi+/PAC10Ph@SPIONs are 17.0 ± 4.4 and 15.0 ± 2.9 % and, therefore, being lower than about 20% for PCB 2. At the previously introduced maximum contaminant level of 0.5 µg L -1 set by the United States Environmental Protection Agency every liter contains about 2.3 nmol of PCBs calculated with the average molar mass of the here investigated pollutants. The SPIONs could be able to adsorb this amount in a single treatment. The performances of the different adsorbent systems for treatment of mixtures of biphenyl and PCBs mostly resemble the trends of the separate extractions. The overall higher removal amounts need to be considered under the influence of in sum higher starting amounts. Hydrophobic segregation leads to PAC16@SPIONs and PAC10Ph@SPIONs extracting the highest amounts of pollutants with biggest share of PCB 14.
