A, B The removal of phenol by Fe(VI)/EDTA, C the rate constants of Fe(VI) reacting with EDTA, and D the in-situ Raman spectra of the Fe(VI)/EDTA system. [Fe(VI)]0 = [EDTA]0 = 50 μM in (B); [Fe(VI)]0 = 50 μM, [Mg(II)]0 = [EDTA]0 in (C); [Fe(VI)]0 = [EDTA]0 = 5 mM in (D). [Phenol]0 = 5 μM. Borate buffer solution of pH 8.0.
