In this paper, the influence of oxidation with hydrogen peroxide onto functional groups content in natural cellulose fibers was studied. Changes in fibers obtained at various modification conditions were evaluated by determination of carbonyl and carboxyl group content in samples before and after modification. Oxidation with H2O2 leads to a significant increase in carbonyl group content already at shorter times and milder treatment conditions. Small change in carboxyl group content occurs at higher pH values (pH 11) and 6 vol % solution concentration. Taking into account nonselective nature of hydrogen peroxide as an oxidizing agent, the optimization of process in accordance with ultimate application of modified cellulose material can be performed by careful selection of oxidation conditions.
