β¦ Synopsis
A general method for determination of the stability constants of complexes of crown ethers and related compounds with small organic molecules in polar solvents is described, based on an indirect polarographic procedure. Computerized evaluation of the data forms an essential part of the procedure.

Two computerized potentiometric methods have been used to determine the stability constants of Na+ , K', and NH: complexes with 18-crown-6 in methanol-water solutions (70% volume fraction of methanol) at 25.0 ? O.l"C, and at constant ionic strength I = 0.1 M, adjusted with tetrabutylammonium iodide
