Table 1

Reactant ratios and synthetic conditions.

Sample	Ferric chloride (g)	Ferrous chloride (g)	Pectin (% w/v)	Starting pH	Ending pH
PIO-1A, PIO-1F	7.8	3.0	0.3	2.5	11
PIO-2A, PIO-2F	7.8	3.0	0.5	2.5	11
PIO-3A,	7.8	3.0	0.8	2.5	11

PIO: “pectin iron oxide,” A for air-dried samples, F for freeze-dried samples.
