MWCNTs based sorbents for nuclear waste management: A review

Multi walled carbon nanotubes (MWCNTs) based adsorbents have high sorption efficacy, fast sorption rate, selectivity, and reusability. All these features highlight that MWCNTs based adsorbents are excellent sorbents for the removal of toxic pollutants like heavy metals, organic pollutants etc. from industrial waste solutions. On the same line, these adsorbents have been utilized for the preconcentration/separation of the f-elements from nuclear waste solutions. This review outlines various methods that have been employed for the preparation of functionalized MWCNTs and MWCNTs based composites. Importantly, here an overview of applications of MWCNTs based adsorbents for the preconcentration/removal of f-elements from nuclear waste solutions have been discussed in detail. The main objective of this review is to provide valuable information on the developments that have been made so far for the separation of lanthanides and actinides from the nuclear waste solutions.
