Sustainable detection and capturing of cerium(III) using ligand embedded solid-state conjugate adsorbent

The detection, adsorption and recovery of rare-earth elements specially the cerium (Ce(III)) on ligand based optical conjugate adsorbent was systematically studied. The functional ligand of 6-((2-(2-hydroxy-1-naphthoyl)hydrazono) methyl)benzoic acid (HMBA) was synthesized and then successfully ancho...
