摘要:

The use of a cellulose ion-exchanger (Hyphan) for the isolation of MnO4−, CrO42-and MoO42-from aqueous solution after reduction with different reducing agents is described. After preconcentration, Mn(II), Cr(III) and molybdenum cations were determined by atomic absorption spectrometry. Furthermore, the distribution coefficients Kdof the investigated cations as a function of pH were studied, and are in the range 104.3−105.9cm3g−1for the above cations.
