Highly efficient surface sequestration of Pb and Cr from water using a MnO anchored reduced graphene oxide: Selective removal of Pb from real water.

Owing to the ubiquitous existence of detrimental heavy metals in the environment, simple adsorption-oriented approaches are becoming increasingly appealing for the effective removal of Pb and Cr from water bodies. These techniques use nanocomposites (NC) of reduced graphene oxide (rGO) and MnO (rGO-MnO), they employ a hydrothermal technique featuring NaBH and NaOH solutions. Here, spectroscopic and microscopic instrumental techniques were used to evaluate the morphological and physicochemical characteristics of prepared reduced graphene oxide manganese oxide (rGO-MnO), revealing that it possessed a well-defined porous structure with a specific surface area of 126 m g.
