“…In this work we investigated the synergistic effect of SRFA and DFOB, at environmentally relevant concentrations, on the solubilisation of Fe(III) and Cr(III) from goethite at pH 6.5. We propose that SRFA enhances the efficacy of DFOB by (i) increasing Krajnc et al (1995), Cornell and Schwertmann (2003), Edwards et al (2005), Cozar et al (2006), Prasad et al (2006), Borer et al (2009), Ohta et al (2011 and Kruft et al (2013). Vibration modes are designated as follows: v, stretching; δ, deformation; s, symmetrical; as, asymmetric.…”
