Resumen

OROZCO-GUARENO, E. et al. Study of acrylic terpolymeric hydrogels swelling in water and aqueous solutions containing lead (II) ions. Rev. Mex. Ing. Quím [online]. 2011, vol.10, n.3, pp.465-470. ISSN 1665-2738.

Hydrogels were synthetized by radical polymerization using potassium persulfate and sodium bisulfiee as redox initiators, acrylic acid, acrylamide and 2-acrylamido-2-methyl propanesulfonic acid as the monomers, and ethylene glycol dimethacrylate as the crosslinksng agent. The swelling capacity of the hydrogels was determined in both water and aqueous solutions containing lead ions (1000 mg L^-1 of Pb⁺², at pH values of 4.0 and 5.0, constant ionic strength I= 0.1 M).

Palabras llave : hydrogel; uptake; lead; acrylic acid; swelling.
