Abstract

Using cocrystallization and conductometry methods Sr{sup 2+} and Eu{sup 2+} complexing with 18-crown-6 in aqueous-ethanolic solutions at (H{sub 2}O)=10 mol/l is studied. Stability constants of Sr{sup 2+} and Eu{sup 2+} complexes with 18-crown-6 in C{sub 2}H{sub 5}OH, for which lg{beta} is equal to (4.76{plus minus}0.12) and (4.72{plus minus}0.13) respectively, are determined. Comparison of the investigated elements features during complexing with 18-crown-6 in aqueous and aqueous-ethanolic solutions is carried out. It is shown that both in water and in C{sub 2}H{sub 5}OH -10 mol/l H{sub 2}O system under Sr{sup 2+} and Eu{sup 2+} complexing with 18-crown-6 the differences in properties of these elements are not detected.
