Abstract

Un filtro absorbente para mover la cafeína de los líquidos. El filtro está compuestos de una matriz tratada con electreto al líquido de material fibroso teniendo superficies individuales uniforma expuestas, una distribucion relativamente uniforme de un material particulado de zoelita absorbente sujetado a superficies expuestas individuales de el material fibroso tratado con electreto mediante la union esencialmente no transitoria, de manera que el paso de un líquido teniendo una concentracion de cafeína variando de desde alrededor de 10 a alrededor de 100 mg por 100 mL de líquido a través de la matriz para un tiempo de contacto de menos de alrededor de 2 minutos resulta en por lo menos una reduccion de 40 por ciento en la concentracion de cafeína de el líquido. la matriz de material fibroso puede seleccionarse de telas tramadas y telas no tejidas. Generalmente hablando, el filtro puede estar adaptado para proporcionar por lo menos 40 por ciento de reduccion en la cafeína por alrededor de 1 taza a alrededor de 40 tazas de un líquido.
