Abstract
AbstractA number of resins were synthesised by reacting 2,4‐dinitrophenylhydrazone derivatives of resacetophenone with substituted aromatic compounds and furfural in the presence of some acid and basic catalysts. The physicochemical properties of the resins are reported. The resins were characterised by their IR and NMR spectra. The ion exchange properties of the resins and the influence of electrolytes on the metal uptake of Cu2+, Co2+, Zn2+, Mn2+ and Mg2+ were studied. The distribution of metal ions at different pH are also reported. The thermal properties of the resins were evaluated by TGA, and kinetic parameters were evaluated using the Freeman–Anderson, Broido, Piloyan–Novikova, Coats–Redfern and Horowitz–Metzger methods.
