Abstract
Based on the finding that dibenzyl ether (DBE) exhibited a relatively high selectivity for ammonium ion relative to potassium ion, four types of dibenzyl ethers were synthesized and their ammonium ion selectivities over alkali and alkaline-earth metal ions were examined with potentiometric measurements.Keywords
