FLAME ATOMIC ABSORPTION SPECTROMETRIC DETERMINATION TRACE AMOUNTS OF NICKEL IN WATER SAMPLES AFTER SOLID-PHASE EXTRACTION AND PRECONCENTRATION ONTO IR-120 AMBERLITE RESIN MODIFIED WITH 5-)4-DIMETHYL AMINO-BENZYLIDENE)-RHODANIN

In the present article, modified IR-120 Amberlite resin was used as sorbent for preconcentration trace amounts of nickel ions. Nickel ion was adsorbed quantitatively onto IR-120 Amberlite resin that modified with 5-)4-dimethyl amino-benzylidene)-rhodanin in the pH range of 5.5-7.0. The adsorbed nick...
