Abstract
Abstract A systematic study of the factors affecting the extraction of strontium, as an ion-pair formed between the positively charged cryptate of strontium with cryptand 2.2.2 and the eosinate anion, into chloroform has been carried out. The p K 1 and p K 2 values of the figand, the stability constant of the cryptate inclusion complex, as well as the partition coefficient and the extraction constant of the ion-pair, were measured as a function of the ionic strength of the solution. The p K a and K s values remained reasonably constant at ionic strength ⩽ 0.1 M. Nevertheless, the partition coefficient values, and consequently the extraction constant values, decrease as the ionic strength increases.
