Correction: Preparation of polyethylenimine and carboxymethyl cellulose co-modified magnetic bentonite for enhanced adsorption of Pb(II) and Cd(II) based on the concept of mesh bag and octopus-like tentacle.

The correction notice for the article "Preparation of polyethylenimine and carboxymethyl cellulose co-modified magnetic bentonite for enhanced adsorption of Pb(II) and Cd(II)" in the journal Cellulose addresses an error in Fig. 3, where the Fe 2p spectra of PEI-MB were incorrectly used for CMC-MB. The corrected version of Fig. 3 is provided in the correction. The original article has been updated to reflect this correction. [Extracted from the article]
