| Abstract: | The contents of Cu,Fe,Mn,and Zn in cobalt nitrate,used for cadmium-nickel cell dipping,were analyzed continuously by flame atomic absorption spectrometry.The interferential factors in the sample were investigated.The results show that the method has the advantages of simplicity,easiness,and less interferences.The RSDs of four elements were less than 1.0%,and the recoveries were in the range of 97.0%~101.0%. |
