Abstract
Rapid oxidation and cationization of cotton was carried out with periodate and Girard’s Reagent T (GT) under microwave irradiation. The degree of oxidation was increased with an increase in microwave irradiation time and in the amounts of periodate, as evaluated by FTIR and chemical methods. Cationization was carried out both under microwave irradiation and at room temperature for comparison. FTIR, dye sorption and elemental analyses substantiated that imine formation between aldehyde and GT was easier at room temperature, probably due to the reverse reaction at high temperature. Nevertheless, cotton cellulose cationized under microwave irradiation exhibited high hydrophilicity and stability, along with antimicrobial properties. Therefore, this study confirms that rapid and efficient oxidation and cationization of cotton is feasible under microwave irradiation and the obtained material could find various end-use applications.
