Se evaluó el poder hipoglicemiante de zeolitas tipo cancrinita intercambiada con iones hierro (II), calcio (II) y magnesio (II) con el fin determinar la influencia de la masa y el tiempo de contacto en la adsorción de glucosa.Inicialmente, se sintetizó la zeolita tipo cancrinita a partir de zeolita X, y se intercambiaron los iones sodio por calcio, hierro o magnesio. Luego, se evaluó el poder absorbente de estas zeolitas en una solución de glucosa. En un primer ensayo, se determinó la influencia de la masa y del catión intercambiado usando masas comprendidas entre 50 y 500 mg, y en un segundo estudio, se determinó la influencia del tiempo de contacto en el proceso de adsorción con una masa inicial de 100 mg, y tiempos de: 15, 30, 45, 60 y 120 min. Los ensayos concluyeron que un aumento de la masa y tiempo de contacto hasta 60 min, favorecen la adsorción de la glucosa, y que las zeolitas intercambiadas con Fe (II) presentaron la mayor adsorción de glucosa respecto a los otros cationes. Con base en los resultados obtenidos, se puede afirmar que estas zeolitas podrían representar una alternativa importante como medicamento novel en la lucha contra la Diabetes Mellitus.
