Efficient detection and extraction of cobalt(II) from lithium ion batteries and wastewater by novel composite adsorbent

Awual, M. R.; Ismael, M.*; Yaita, Tsuyoshi

The composite adsorbent was prepared by indirect immobilization of 6-((2-(2-hydroxy-1-naphthoyl)hydrazono)methyl)benzoic acid (HMBA) onto mesoporous silica monoliths. The composite adsorbent enhanced the color formation by stable complexation as [Co(II)-HMBA] $^{n+}$ complexes during detection and sorption operations. The effective pH range for Co(II) ions detection and sorption was neutral pH region and the maximum sorption capacity of the adsorbent was as high as 189.37 mg/g.
