| Popis: | 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% HNO3 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. Keywords: extraction, preconcentration, fatty hydroxamic acid, copper (ii) ion, amberlite XAD-4 |
