5. Determination of protolytes by flow procedures : applications to liquors from the hydrometallurgical nickel industry
Abstract : The general intention of this work is to contribute inreplacing complicated and time consuming titration methods foracid/base determination in cases where a rapid answer is morevaluable than a very high accuracy. The versatility of FlowInjection Analysis (FIA) is utilised for the determination ofprotolyte compounds, considering their role in our daily lifeas well as in science and technology. READ MORE
