SEPARATION AND PRECONCENTRATION OF COPPER (II) ION BY FATTY HYDROXAMIC ACIDS IMMOBILIZED ONTO AMBERLITE XAD – 4 RESIN
ABSTRACT: A method of copper
(II) ion preconcentration and separation from other ions by using a column
containing fatty hydroxamic acids – loaded Amberlite XAD 4 resin (FHA-Amb) is
described. Several factors, which affect the separation and preconcentration
efficiency such as pH, sample volume, and concentration of eluent and flow rate,
have been investigated. A quantitative recovery of copper (II) ion from FHA-Amb
resin column was obtained using 10% HNO 3 solutions as eluent with a
preconcentration factor of 60. A method for separation of Cu(II) from Zn(II) and
Cd(II) is proposed. A rapid sample throughput, a clean separation, a high
preconcentration factor and simplicity are the main advantages in these
analytical procedures.
