| Abstract: | In this study the authors look at fractionation at a very low pH.[1] The problem was to separate nickel sulfate from sulfuric acid, or from nitric acid, when it was the single salt in solution, or when it was present together with other salts as in the case of a rinsing water used in the mining industry. |
