LEON FERNANDEZ, Vivian et al. MODIFIED BAGASSE, ITS POTENTIAL AS DECOLORANT IN THE SUGAR INDUSTRY. cen. az. [online]. 2015, vol.42, n.2, pp. 31-38. ISSN 2223-4861.

In this paper, the conditions for obtaining an anionic exchanger based on the chemical modification of the fibrous fraction of bagasse by etherification in basic medium are studied. It evaluates the influence parameters concentration of sodium hydroxide, the molar ratio cellulose/diethylaminoethylamine hydrochloride and the reaction time in the substitution. In each case a degree of substitution estimated by determining the nitrogen content was obtained. It has been demostrated that the product removed 40-60 % of color in sugar solutions, therefore can be used in the sugar industry for the removal of ionic compounds.

Palavras-chave : bagasse; decolorization; ionic exchange.
