B DETERMINATION OF COPPER BY ICP-OES

1 Solutions with copper compounds are nebulised into an argon plasma, where all components are vaporised. Copper compounds are dissociated and excited, and then emit radiation of which the intensity is measured at a wavelength of 327.395 nm. 

1 This procedure yields a standard curve that is linear up to at least 2 mg/L Cu. 

1 The reproducibility of determinations by this procedure should give, at reasonable control and thorough sample preparation, a coefficient of variation within 5 % + 5 mg/kg. 

1 Inductively coupled plasma optical emission spectrometer.
