AbstractAbstract
[en] The interfacial properties of 8-hydroxyquinoline (HOX) and /or some crown ethers; Db 18 C6, 18 C6 and 15 C5 at the chloroform/ nitrate interface were investigated by measuring their interfacial tension using Du Nouy ring method. The data indicate that 18 C6 and 15 C5 have variable effects on the chloroform-nitrate interface according to their concentrations while Db 18 C6 and HOX have nearly no effect at the interface in the investigated concentration range. The mixture of HOX and 18 C6 or 15 C5 showed different trends according to their concentrations. The proposed mechanisms were verified by carrying out Co(II) extraction by HOX-Db 18 C6 mixture in chloroform in the low and high concentration ranges at different interfacial area. The use of benzene instead of chloroform indicate that the nature of diluent has a marked effect on the interfacial properties of 18 C6 and 15 C5 while Db 18 C6 was found to be sparingly soluble in benzene in the investigated concentration range
