Successive Test on the Content of Copper Manganese Cadmium Nickel Iren in Waste Water

Zhou La-mei

Abstract

A method of FAAS(Flame Atom Absorption Spectrum) detrmination of Cu?Fe?Mn?Cd?Ni in the water desribed. The water sample was digested with mixture acid of HNO 3-HCLO 4-HCL.The elements mentioned above were determined by FAAS. The RSD's (Relative Standard Deviation) of the method ware found to be within the rang 1.08 %～3.1 % and the recycle rate were 96 %～105 %.
