| Abstract: | The sorption of polyionene 1,4-MePh on the silica gel surface was studied. The silica gel modified with polyionene sorbed was used for sorption preconcentration of MoO 4 2? , WO 4 2? , Cr2O 7 2? , and VO 3 ? anions from aqueous solutions. The sorption isotherms of these anions on the initial and modified silica gels were obtained and analyzed. |
