Abstract

Correction for ‘Reusable bentonite clay: modelling and optimization of hazardous lead and p-nitrophenol adsorption using a response surface methodology approach’ by Mohamed Zbair et al., RSC Adv., 2019, 9, 5756–5769.

In the published article there was an error in the naming of the pollutant Pb2+ in Table 9 on p. 5763. The correct version of this table is shown here below.
