Figure 3

(a) Dissolved iron concentration in carboxylate@MNP dispersions (10 g/L in 0.01 M NaCl solution at pH ~6) in the function of the amount of added carboxylates, CA, GA, PAA and PAM. The lines are drawn to CA and PAA data to guide the eyes. The error bars are omitted for the sake of clarity. The dotted line indicates the iron detection limit; (b) Specific magnetization curves measured in the dispersions of CA and PAA coated MNPs (100 g/L in water at pH ~6) at different added amounts of the carboxylates.
