| Abstract: | The application of separation and enrichment technology in determination of trace ferrum in nickel aminosulfonate solid is studied. Using ethyl acetate for extraction separation and 1,10 -phenanthroline colorimetrie method, the ferrum in nickel aminosul- fonate is determined with the standard recovery of 94. 5% - 103.2% and relative standard deviation of 15.1%. The degree of accuracy and precision can meet the demand of controlling analysis in nickel aminosulfonate production. |
