Abstract
Correction for ‘Adsorption of safranin-O dye on CO2 neutralized activated red mud waste: process modelling, analysis and optimization using statistical design’ by Manoj Kumar Sahu et al., RSC Adv., 2015, 5, 42294–42304.
The authors wish to amend an incorrect statement in Section 3.1 of the original article. On page 42296, right-hand column, line 17, the sentence beginning “Additionally, the band at...” should be replaced with the following: “Additionally, the band at 3292 cm−1 is attributed to N–H group of safranin-O dye adsorbed on the surface of the red mud. The mechanism of adsorption of safranin-O dye on activated red mud (ARM) can be illustrated in Fig. 4”.
Furthermore, the image presented for Fig. 4 in the original article inaccurately represents the proposed adsorption mechanism. The amended image for Fig. 4 is shown below.
