A method for the determination of lead, cobalt, nickel, chromium, zinc and manganese in iron minerals siderite (FeCO3), hematite (Fe2O3), pyrite and marcasite (FeS2)by flame and Zeeman electrothermal atomic absorption spectrometry (ETAAS) was developed. Interferences were investigated by measuring the absorbance of the elements investigated in series of samples with varying mass ratios of the e...
