Organic and inorganic based conjugate materials are important in nanotechnology based on the high functionality and stable complex formation with target metal ions at optimum conditions. A new ligand immobilization based dual and tunable conjugate adsorbent was investigated under specific solution acidity for detection and removal of Co(II) and Cu(II) ions. Under the optimum conditions, the calibration graphs were the linear and detection limit which were 0.52 and 0.41 ppb for Co(II) and Cu(II), respectively. The removal efficiency was carried out as a function of solution pH, initial metal ions concentration, and co-existing diverse ions. Sorption equilibrium was well fitted to Langmuir isotherms and determined sorption capacity was 205.33 and 199.20 mg/g for Co(II) and Cu(II), respectively.
