چکیده
|
The potentiometrical analysis of cu2+ using nafion- modified electrode with cucomplex with dpaba (methyl 3,5-bis{bis-[(pyridin-2-yl)methyl]amino}methyl)benzoate)incorporated, is described. parameters and conditions such as the volume of 2% nafion, ph,and the concentration of cu complex with dpaba and ph of medium were optimized.interference of fe3+, co2+ and zn2+ with cu2+ were examined. calibration curve was linear inthe range of 1×10-7-5×10-5 mol/l. the detection limit was 7×10-8 mol/l. a response time ofthe proposed electrode was 3 s.
