Membrane Filtration of Nickel(II) on Cellulose Acetate Filters for Its Preconcentration, Separation, and Flame Atomic Absorption Spectrometric Determination
10.1002/clen.200900189.abs
An enrichment method for trace amounts of Ni(II), as 8‐hydroxyquinoline chelates, has been established on a cellulose acetate membrane filter. Ni(II)‐8‐hydroxyquinoline chelates adsorbed on a membrane filter were eluted using 5 mL of 1 M HNO3. The eluent nickel concentration was determined by a flame atomic absorption spectrometer. The influence of some analytical parameters, including pH, amount of reagent, sample volume, etc., on recovery was investigated. The interference of co‐existent ions was studied. The nickel detection limit was 4.87 μg/L. The method was applied to real samples for the determination of nickel(II) ions.
