摘要:
Cation exchange equilibrium distribution coefficients are presented for the chloride complex forming elements Hg(II), Bi(III), In, Cd, Pb(II), Fe(III), Ga, Zn, Cu(II) and Te{IV) with a macroporous (macroreticular) cation exchange resin in nitric acid of concentrations ranging from 0.20 to 5.00 M.Known distribution coefficients (from the literature) for similar concentrations of hydrochloric acid are included for comparative purposes and the influence of chloride complex formation is discussed. Separations which are possible by using both HC1 and HNO3as eluting agents are demonstrated by two elution curves separating the mixtures Hg(II)-Bi(III)-Zn-Pb(II); and Tl(III)-Bi(III)-Cu(II)-Fe(III).
