The results suggest that the complexes have a 1:1 (metal ligand) molar ratio, involving mononuclear azo ligand with:an ONO donor set Metal ion uptake studies were conducted with a batch technique The results indicate that the azo ligand has high thermal stability and good metal extraction capacity.eninfo:eu-repo/semantics/openAccessAzo ligandMetal complexesMetal ion uptakeThermal stabilityArticle2672161216510.14233/ajchem.2014.168282-s2.0-84901020170Q4WOS:000336777300064N/A
