摘 要:Atomic absorption and plasma arc spectroscopy were used to determine the contents of Ca,Mn,Cu,Ni,Co,Pb,Zn,Fe,Mg,Hg,Mo,Cr,totally 12 macro and trace elements in yellow,white and black pearls.The results showed that all the three kinds of pearls contained Ca of more than 3×104 mg/100g.The contents of Mn,Cu,Fe,Mg were above 1mg/100g.Ni,Co,Pb,Mo,Cr,Zn had less contents in the pearls,and Hg had the least.It was also showed that Mn,Cu,Pb,Zn,Mg,Co and Cr contents in different colorpearls varied greatly.Atomic absorption and plasma arc spectroscopy were used to determine the contents of Ca,Mn,Cu,Ni,Co,Pb,Zn,Fe,Mg,Hg,Mo,Cr,totally 12 macro and trace elements in yellow,white and black pearls.The results showed that all the three kinds of pearls contained Ca of more than 3×104 mg/100g.The contents of Mn,Cu,Fe,Mg were above 1mg/100g.Ni,Co,Pb,Mo,Cr,Zn had less contents in the pearls,and Hg had the least.It was also showed that Mn,Cu,Pb,Zn,Mg,Co and Cr contents in different colorpearls varied greatly.
