Abstract

Correction for ‘Removal of Pb(ii) and Cd(ii) from wastewater using arginine cross-linked chitosan–carboxymethyl cellulose beads as green adsorbent’ by Kaiser Manzoor et al., RSC Adv., 2019, 9, 7890–7902.

The authors regret that an incorrect version of the SEM image shown in Fig. 3b was included in the original article. The correct version of Fig. 3 is presented below.

Fig. 3. SEM micrographs of (a) CS, (b) CM, (c) CS-ag-CM, (d) Pb(II)/Cd(II)-CS-ag-CM(e) Pb(II)/Cd(II)-CS-ag-CM and EDX spectrum of (f) CS-ag-CM and (g) Pb(II)/Cd(II)-CS-ag-CM.

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