| Abstract: |
| Nickel (Ni), cobalt (Co) and manganese (Mn) content in ternary precursor Ni0.33 o0.33Mn0.33(OH) 2 was determined by instrumental and chemical analyses. The?molar proportion of Ni, Co and Mn was determined by ICP-AES and the total content of the three elements was determined by EDTA titration. Then Ni, Co and Mn content was calculated. Higher precision was obtained by optimizing the experimental conditions. A recovery between 99.2% and 101% was achieved, and the relative standard deviation was lower than 0.65%. The established method is accurate, fast and has been applied to practical analysis. |
