Abstract

A simple, reliable and sensitive spectrophotometric method for the determination of copper(II) was established with o-bromophenylfluorone (OBPF), a novel chemical probe, in the presence of poly(N-vinylpyrrolidone). Beer's law was obeyed in the range of 8 - 160 ng ml -1 , with an apparent molar absorptivity at 570 nm, the relative standard deviation being 3.64 × 10 5 dm 3 mol -1 cm -1 and 0.72% (n = 5). This method was applied to the recovery tests of copper(II) in human urine, bovine serum and tap water; the results were satisfactory. 2009
