Abstract
The widespread application of hydrogels bead in a number of application like separation,
adsorption, filtration, agriculture and drug delivery make it important to property understand the
swelling properties of these materials. Typically, gel size and swelling capacity are sensitive to
outer solution pH. In this paper, the study of the swelling capacity of the commercial polyacrylic
acid hydrogel bead was investigated as a function of time and pH. The diameter, weight, degree of
swelling, water retention as well as the fractional hydration were studied to predicate the swelling
properties of hydrogel bead at a given pH. The type of diffusion and its related parameter diffusion
exponent (n) and diffusion constant (k) were studied and calculated.
