Abstract

Una pastilla de filtro adsorbente comprimida para remover la cafeína de los líquidos. La pastilla de filtro está compuesta de una matriz comprimida de material fibroso; y el material particulado absorbente integrado dentro de la matriz comprimida del material fibroso, de manera que el paso del líquido teniendo una concentracion de cafeína variando de desde alrededor de 20 a alrededor de 100 mg por 100 mL del líquido a través de la matriz por un tiempo de contacto de menos de alrededor de 2 minutos resulta en por lo menos una reduccion de 40% en la concentracion de cafeína del líquido. La matriz comprimida del material fibroso puede ser una estera fibrosa colocada en humedo y comprimida. El material absorbente puede ser seleccionado de minerales de arcilla y zeolitas. Generalmente hablando, el filtro puede estar adaptado para proporcionar por lo menos una reduccion de 40% en la concentracion de cafeína para alrededor de 1 taza alrededor de 40 tazas de un líquido.
