Abstract

Correction for ‘3D nitrogen-doped graphene gels as robust and sustainable adsorbents for dyes’ by Jiyu Geng et al., New J. Chem., 2017, 41, 15447–15457.

The authors would like to correct Table 3, as the data for methyl orange are incorrect in the published article. The correct Table 3 is shown below.

Table 1 Langmuir and Freundlich isotherm parameters of NG-2, NG-6, and NG-12

Isotherm model	Parameters	MB			MO
Isotherm model	Parameters	NG-2	NG-6	NG-12	NG-2	NG-6	NG-12
Langmuir	q _m (mg g⁻¹)	156.25	77.17	14.22	56.18	227.27	175.44
	K _L (L mg⁻¹)	2.67	0.21	0.46	0.22	2.75	0.32
	R _L	0.02	0.19	0.10	0.19	0.02	0.14
	R ²	0.9985	0.9968	0.9956	0.9913	0.9987	0.9990

Freundlich	K _f (mg g⁻¹) (L mg⁻¹)^1/n	119.43	14.17	1.47	18.08	197.74	61.05
	n	2.89	3.01	6.71	3.22	23.15	3.08
	R ²	0.9949	0.9824	0.9667	0.9782	0.8686	0.9289

The authors would like to correct Fig. 5, as the x-axis labels in Fig. 5a and b and the figure caption are incorrect. The correct Fig. 5 and caption are shown below.


	Fig. 1 Adsorption curves of (a) MB and (b) MO on NG-2, NG-6, and NG-12; pseudo-first-order kinetic plots with (c) MB and (d) MO on NG-2, NG-6, and NG-12; and pseudo-second-order kinetic plots with (e) MB and (f) MO on NG-2, NG-6, and NG-12.

Corrections have also been made to Fig. S7–S9 and Table S3 in the ESI. The ESI was updated on 22nd December 2017.

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