Determination of Trace Elements in Powdered Milk by Neutron Activation Analysis

Eight trace elements (Co, Cu, Zn, As, Cd, Sn, Sb and Hg) in powered milk have been determined simultaneously by neutron activation analysis with chemical group separation. The irradiated samples were digested with a mixture of HNO3 and H2O2 in a reflux system and subjected to the group separation. T...

Description
Summary:Eight trace elements (Co, Cu, Zn, As, Cd, Sn, Sb and Hg) in powered milk have been determined simultaneously by neutron activation analysis with chemical group separation. The irradiated samples were digested with a mixture of HNO3 and H2O2 in a reflux system and subjected to the group separation. Then γ-rays from the radioactive products were measured with a Ge (Li) detector coupled with a 4096 channel pulse height analyzer. The powdered milk samples investigated have been found not to contain heavy metal elements over the warning levels. This method has been shown to be useful for simultaneous determination of heavy metals in biological materials.
