Aliphatic and aromatic polymeric resins of (2-hydroxybenzaldehyde) with 1,2-propylenediamineand 1,4-phenylenediamine were synthesised and characterised employing elemental and thermal analysis,FT-IR and UV-visible spectroscopy. The metal uptake behaviour of synthesised polymers (PMBHBPn,PMBHBPh) towards different metal ions were investigated and optimised by variety of conditions. Thesorption data of these metal ions were followed Langmuir, Freundlich, and Dubinin-Radushkevich(D-R) isotherms. The Freundlich parameters were computed at 1/n = 0.26 ± 0.02, 0.309 ± 0.02, 0.35 ±0.05, 0.368 ± 0.04 and 0.23 ± 0.01, A = 3.9 ± 0.03, 4.31 ± 0.02, 4.683 ± 0.01, 5.43 ± 0.03, and 2.81 ± 0.05mmol/g for Cu(II), Co(II), Ni(II), Fe(III) and Cd(II) ions, respectively. The variation of sorptionwith temperature gives thermodynamic quantity (DH) in the range of (AH = 36.33 - 52.14 KJ/mol) for(PMBHBPn) and (39.21-56.29 KJ/mol) for (PMBHBPh). The sorption procedure could preconcentratemetal ions, and it can be determined by atomic absorption spectrophotometer.
