WebFh was synthesized according to Hiemstra et al. (16) Briefly, ∼1.0 L of a solution containing ∼3.7 mM Fe (NO 3) 3 ·9H 2 O dissolved in 0.01 M HNO 3 was titrated by adding a freshly prepared solution of 0.02 M NaOH. The NaOH solution was initially added at a rate of ∼200 mL min –1 until a pH of ∼3.1 was reached. hcss hitachi
