- Abstract
The present paper is devoted to sorption concentration of copper (II) from different solutions on a number of complexing ion exchangers and subsequent determination of Cu (II) in a phase of amphoteric ion exchanger AMF-2T of macroreticular structure by diffuse reflectance spectroscopy. The sorption properties of the sorbents were investigated. The apparent stability constants for copper complexes in ion exchanger phase were calculated. The sorption-spectroscopic method is proposed for Cu (II) determination in aqueous solutions. The calibration curve is linear at concentration range 0.05 - 3.0 mg/L (sample volume is 25.0 mL) and the detection limit is 0.03 μg/mL. The presence of Ni (II), Co (II), Cr (III), Fe (II,III), Zn (II) as well as C2O42-and PO43-(100-fold excesses) does not hinder the determination of Cu (II).
