Abstract. This paper presents the results of studies of the oxidation reaction of carboxymethylcellulose (Na-CMC) with sodium periodate using microwave irradiation. The influence of reaction time, oxidant concentration, solution pH and reaction temperature to the content of aldehyde groups in the product and the reaction yield were studied. The physicochemical properties of the obtained samples were studied by chemical, IR-spectroscopic and thermogravimetric analysis methods. As a result of periodate oxidation of Na-CMC in a microwave irradiation high degree of oxidation samples were obtained.
