| dc.description.abstract | In this paper kinetics of binding of fullerol to polyacrylic hydrogel at different temperatures, 298, 308 and 318 K, has been investigated. Time dependences of specific capacity of fullerol binding to hydrogel at defined temperatures are determined. Kinetic curves of specific binding capacity of fullerol for hydrogel are described by equations: x = k(1)x(2)max(t)/1+k(1)xmax(t) and x=k(2)t(n). Rate constants k, and k2 of the specific ftillerol binding capacity at various temperatures are determined. Based on changes in constants k(1) and k(2) with temperature, kinetic parameters of the investigated process are calculated. Also, due to a great difference in values of kinetic parameters k(1) and k(2) obtained by varying the temperature, kinetic parameters are determined by using Friedman's isoconversion method. The values of kinetic parameters based on temperature changes in k(2) correspond to the values of kinetic parameters for alpha approximate to 0.9, while the values of kinetic parameters calculated according to the temperature change in k(1) correspond to the E-a values. According to the obtained results it is concluded that the investigated process is controlled by diffusion. | en |
