Abstract:A sensitive analytical method of trace impure elements in red lead (Pb 3O 4) by ICP AES after separated from tri phase extraction has been studied, such as Fe?Cu?Ni?Co?Mn?Zn?Cd etc. The dioturbances of determined elements from lead matrix are inspected. The detection limits of the method is 0.06~0.6μg/g. The rates of standard additions recovery are all higher than 87%, RSD are varied within 10%.
Key words:tri phase extraction; impure elements; Pb 3O 4
