• selectivity coefficients for Ag+ cations were investigated against alkali metal, alkaline-earth metal, lead, ammonium ions and some transition metal ions using the fixed interference method (FIM) [54][55]. Firstly, the response characteristics of Ag+-ISEs based on different ionophores were tested. It was
