| Abstract | ||
| a simple and sensitive spectrophotometric method has been developed for determining copper (II) with Murexide and this method depends on formation of a stable yellow greenish colored complex at pH=5 where it has a maximum absorption at 476 nm , the optimal conditions for the formation of complex were studied . It appeared that the complex real-time, stable complex consists for 30 days . the molecular ratio was identified by the continuous variation method and mole ratios . the ion reactive ratio ( ion : Reagent ) were 1:2 , Lambert beer's law obeyed in concentration range of 10 - 80 μg.ml-1 , relative standard deviation 1.04% , Limit of detection 0.31 μg.ml-1 and molar absorptivity was 1.2x105 L.mole-1.cm-1 . By this method could determine copper (II) with high precision , accurate and sensitive and agree on high-water samples. | ||
