Title:
METHOD FOR SELECTIVELY AND COMPETITIVELY SEPARATING OBJECT ION FROM MIXTURE OF OBJECT ION WITH ANOTHER IONS
Document Type and Number:
Japanese Patent JP2681460
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To efficiently separate an object ion from a mutli-ion solution under selective and competitive conditions by allowing a specific compound having an exchangeable or ionizing proton forming part of a large ring compound having a liphophlic group combined with the molecule to contact with the object ion to from a complex.
SOLUTION: In the case of separating the selected ion from plural ions in the multi-ion solution, the compound selected from a group composed of formula I to formula III forms the complex with the selective ion. Where, in formula I, (n) expresses the integers of 1-4 and R expresses C6-18H13-37, in formula II, (n) expresses the integers of 1-3 and R expresses C6-18H13-37 and in formula III, X expresses O or Si, (n) expresses the integers of -1 to 3 and R expresses C6-18H13-37. The multi-ion solution is brought into contact with the compound under the condition of removing the selected ion from the mutli-ion solution. As a result, the object ion is efficiently separated from the mutli-ion solution under the selective and competitive conditions.
