Atomic absorption method determination of copper content of pyrite. The pyrite copper content was analysed by the use of atomic absorption spectrophotometry . The samples were dried , milled ,dissolved by acid ,and analysed by flame atomic absorption spectrometry. The effect of Fe3 +, Zn2 +, and Pb2 + on copper determination was also evaluated which indicated that Fe3 +, Zn2 +, Pb2 +,and Mg2 +content of 3mg/ml, 2.5mg/ml, 1mg / ml, respectively , has almost no influence on the determination. |
