Hidrogeles superabsorbentes basados en poliacrilamida para aplicación agrícola: estudio de hinchamiento
Palavras-chave:
hidrogeles superabsorbentes; agricultura; sequía; hinchamiento.Resumo
Se producen hidrogeles de poliacrilamida mediante síntesis y reticulación simultáneas inducidas por radiación gamma de una fuente de 60Co, a partir de una disolución monomérica de acrilamida 1,26 M. Los hidrogeles obtenidos se modifican químicamente mediante hidrólisis básica incompleta con hidróxido de potasio, para lograr un copolímero de poli(acrilamida-co-acrilato de potasio). El proceso de hinchamiento de las muestras se ajusta a modelos de cinética de primer orden en agua destilada y de segundo orden en condiciones de pH ácido y básico a fuerza iónica constante. Los mejores valores de hinchamiento se obtienen para las muestras irradiadas a 10 kGy y modificadas con hidróxido de potasio durante 1 h, alcanzando estas una ganancia de más de 1000 veces su peso en agua destilada, mientras que en los tampones de pH este valor excede ligeramente la capacidad de absorción óptima para un hidrogel agrícola, aumentando más de 60 veces su peso.
