Sorption of heavy metal ions by cellulose modified with fullerene

Sorption of heavy metal ions by cellulose modified with fullerene Celulose was modified by impregnation of the polymer with a solution of C60 nanocarbon particles in ortho-xylene. Specific features of the sorption kinetics of Cu(II),Ni(II), and Cd(II) ions on cellulose and composite materials were researched. Pseudo-first- and pseudo-second-order kinetic models were used to determine the quantitative characteristics of the process.

The improvement of the sorption properties of the modified polymer is due to the increase in the concentration of active sorption properties and to a change in the structure of the sorbent. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Applied Chemistry Springer Journals

Abstract

Celulose was modified by impregnation of the polymer with a solution of C60 nanocarbon particles in ortho-xylene. Specific features of the sorption kinetics of Cu(II),Ni(II), and Cd(II) ions on cellulose and composite materials were researched. Pseudo-first- and pseudo-second-order kinetic models were used to determine the quantitative characteristics of the process. It was demonstrated that the sorption efficiency of metal ions on fullerene-containing cellulose substantially increases. The improvement of the sorption properties of the modified polymer is due to the increase in the concentration of active sorption properties and to a change in the structure of the sorbent.
