Abstract:
An on-line spectrophotometric method for the determination of copper has been
developed. Cu(I) was complexed with 2, 9-dimethyl-1, 10-phenanthroline (Neocuproine) and
the absorbance of Cu(I)-Neocuproine complex was then measured continuously at 456 nm.
Cu(II) was off-line reduced to Cu(I) by ascorbic acid. The system was automatically controlled
by the program. The parameters such as flow injection parameters, pH and reagent concentrations
were optimized. Analytical performance of the system was investigated and the linear calibration
curve was found in the range of 0.10 mg/L to 5.0 mg/L (y =1.641x+0.074, r2 = 0.994). The limit
of detection, LOD (3 sd/slope) of 0.10 mg/L and the relative standard deviation (RSD) within 5%
(at 2.0 mg/L, n=10) were provided. Automation of the system enabled us to get the sample
injection frequency up to 60 injections/hour. No major interferences such Fe2+, Mg2+ and Zn2+
were observed. The developed method will be applied to the determination of copper in water
samples.
