Abstract
Correction for ‘Removal of Cu(II) from aqueous solution using Fe3O4–alginate modified biochar microspheres’ by Changjiang Yu et al., RSC Adv., 2017, 7, 53135–53144.
The authors regret that there were some errors in the XRD analysis for SiO2 in the original article (p. 53142, Section 3.6.4). The two sentences beginning ‘The diffraction peaks at 2θ = 22.0° and 42.0°…’ are corrected as follows:
“The diffraction peaks at 2θ = 20.9°, 40.3° and 42.5° are assigned to the (1 0 0), (1 1 1) and (2 0 0) planes, respectively. The angular position of the diffraction line corresponded to the amorphous structure SiO2, in accordance with the database of the SiO2 standard card (JCPDS no. 65-0466)”.
The correspondingly updated Fig. 11 is presented below.

In addition, there was an error in the variable name of the right-hand y-axis of Fig. 4. The updated figure, in which ‘DTG’ has been revised to ‘Derivative weight’ is presented below.

The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
