    INVESTIGATION ON THE EXTRACTION OF Y~(3+) ,Eu~(3+) and La~(3+) WITH DIAMIDE FROM NITRIC ACID SOLUTIONS

    • Using suitable organic solvents as diluent,Y 3+ ,Eu 3+ and La 3+ can be extracted effectively by N,N' dimethyl N,N' dioctyl 3 oxy glutaramide without large anion from nitric acid solutions.The effects of the concentration of the nitric acid,salt agents and Eu 3+ in aqueous phase,and the extractant in organic phase on distribution ratioes are researched.The extractive mechanism is examined.The extractablity and selectivety of this extractant for trivalent rare earth ions are better than those of pentaalkylpropane diamides.
