Abstract
The following three extractants were synthesized: C12H25-O(-CH2CH2O-)n CH2-C6H3(OH)(NO2) (n = 3, 6, 9). The extraction constants for alkali m etal ions were also determined. The extractability with an extractant having three oxyethylene units decreases in the order Li+ > K+ > Na+ > Cs+ greater than or similar to Rb+; for other extractants, K+ > Rb+ > Cs+ > Na+ > Li+.
