Effect of solid material on the final total organic carbon content.

	MPS-O3	MPS/Fe-O3	NP-Fe	O3
Total organic carbon (mgL^−1) 20 min	272 ± 5	48 ± 5	80 ± 5	202 ± 5
Total carbon (mgL^−1) 20 min	274 ± 5	50 ± 5	82 ± 5	205 ± 5
Inorganic carbon (mgL^−1) 20 min	3 ± 5	1 ± 5	3 ± 5	3 ± 5

Initial total organic carbon = 202 ± 5 mgL⁻¹.
