Hi for all,

           I was assigned to find 6 methods to increase EDTA selectivity. Till now I have found only 3 methods which are: controlling the pH, precipitation of interfering cations and complexation.

Please if you know the 3 remaining methods, write them down and how can i find their explanation.
                         
                                                          Many thanks! and Waiting for replies.
