Correction: Ascorbic acid/Fe0 composites as an effective persulfate activator for improving the degradation of rhodamine B

Correction for ‘Ascorbic acid/Fe⁰ composites as an effective persulfate activator for improving the degradation of rhodamine B’ by Xiangyu Wang et al., RSC Adv., 2018, 8, 12791–12798.

The authors regret that the unit on the x-axis of Fig. 1 was incorrectly written as “% wt” rather than “‰ wt” in the original article. The correct version of Fig. 1 is presented below.Open in a separate windowFig. 1(a) Comparison of removal efficiency of RhB in different systems (C₀ = 50 mg L⁻¹, PS dosage = 1.4 g L⁻¹, Fe⁰ dosage = 1 g L⁻¹, H₂A/Fe⁰ dosage = 1 g L⁻¹, H₂A dosage = 1.6 g L⁻¹ and T = 298 K); (b) effect of H₂A concentration on removal efficiency of RhB in the H₂A/Fe⁰–PS system (C₀ = 50 mg L⁻¹, Fe⁰ dosage = 0.8 g L⁻¹, T = 298 K and the solution volume is 50 mL).The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
