内容記述 | The extraction of alkaline earth metal ions has been investigated using a mixture of polyethylene glycol mono-p-nonylphenyl ether (PEGP; average number of oxyethylene group, 10) and 4-(1,1-dimethyl-3,3-dimethylbutyl)-2,5-dinitrophenol (2,5-dinitro-4-t-octylphenol, DNP; HL) in_1,2-dichloroethane. The metal extraction takes place with one molecule of deprotonated DNP (L^−) and an extraneous monoanion (X^−) for neutralization of the dicationic charge of the metal ion. The ease of extraction generally follows the order, Ba^2+>Sr^2+>Ca^2+>>Mg^2+. The nature of the anion present in the aqueous phase strongly affects the extractability. For barium, the extractability decreases in the order ClO_4^−>SCN^−>I^−>Cl^−>NO_3^−. The composition of the extracted complexes for barium and strontium ions proportional to the metal is metal : PEGP : L^− : X^−=1 : 1 : 1 : 1. The overall extraction constants were estimated. | |||||
