A 24-1 fractional factorial design was used to evaluate the effect of some parameters; such as the acrylic acid (AA)/chitosan (CTS) molar ratio; crosslinker concentration; initiator concentration; and filler concentration; in the swelling capacity of superabsorbent hydrogel composites based on CTS-graft-poly(acrylic acid) and nontronite clay. The data from wide-angle X-ray scattering and Fourier transform infrared spectroscopy confirmed the syntheses of the hydrogel composites. Main and interaction effects were analyzed by analysis of variance; F tests; and p values. We found that the AA/CTS and crosslinker were the most influential effects in the evaluated response. The proposed statistical model presented a high coefficient of determination (R2 = 0.985). In addition to the swelling kinetics; the effects of pH and salt for the both compositions (with and without filler); which presented the best water uptake; were evaluated. Both hydrogels showed responsive behavior in relation to the pH and the salt solution; presenting good potential for application as devices in the controlled release of solutes. © 2012 Wiley Periodicals; Inc;
