Abstract: The paper is concerned with preliminary studies on new macrocycles-“monomers and dimers”-containing spiro-1,3-dioxane units as ionophores for poly(vinyl chloride) membranes for potentiometric sensing of sodium, potassium, calcium and magnesium ions. The best macrocycles were evaluated for each cation. The optimum membrane composition and the appropriate preparation procedure for obtaining the electrodes with good electrochemical characteristics were closely followed. | |||||||
