D. Siswanta et al., NOVEL AMMONIUM IONOPHORES BASED ON GLYCOL DIBENZYL ETHERS FOR AN ION-SELECTIVE ELECTRODE, Chemistry Letters, (5), 1994, pp. 945-948
Based on the finding that dibenzyl ether (DBE) exhibited a relatively
high selectivity for ammonium ion relative to potassium ion, four type
s of dibenzyl ethers were synthesized and their ammonium ion selectivi
ties over alkali and alkaline-earth metal ions were examined with pote
ntiometric measurements.
