A new radiometric titration method based on separation by means of ion exchange
- 30 Downloads
The determination of zinc with EDTA is chosen as an example for the earlier suggested new radio-complexometric titration procedure, in which phase separation is achieved by means of a strongly basic anion exchanger in the solution. Concentrations of zinc solutions down to 10−6M have been determined. The reverse titration,viz. of EDTA with zinc solution, which can be used as back-titration in complexometry, is also possible. However, theoretical relations for this latter type of titration are not simple.
