Abstract

deed-of-separationA new study for separation and pre concentration of Cd(II) in water samples was done using adsorbant solid phase containing amberlit resin XAD-16 that impregnated with mixed ligands; 1,4-diamino antraquinone and 1,4-dihydroxy antraquinone with ratio 1:1. The solid phase was packed into mini column (10cm length and 5mm diameter) and water sample containing Cd(II) was passed through the column. Then, adsorbed ions were eluted using HCl (2M) as eluent and subsequent determination was done with flame atomic absorption spectrometer (FAAS).For access to the highest recovery, various parameters such as PH, ionic strength,type of eluent, sample flow rate and eluent flow rate were optimized. In this maner, the recovery obtained was quantitative (95%) and LOD (3Sb/m), RSD were obtained 1.2 ×10-9 M, 3.2% respectively.
