ABSTRACT:
An adsorbent filter for removing caffeine from liquids. The filter is composed of a liquid permeable matrix of fibrous material having individual exposed surfaces; and a distribution of adsorbent clay minerals attached to individual exposed surfaces of the fibrous material by substantially non-transient bonding, so that passage of a liquid having a caffeine concentration ranging from about 20 to about 100 mg per 100 mL of liquid through the matrix for a contact time of less than about 2 minutes results in at least a 40 percent reduction in the caffeine concentration of the liquid. The matrix of fibrous material may be selected from woven fabrics, knit fabrics and nonwoven fabrics. The adsorbent clay minerals include, for example, sodium bentonite clays, calcium bentonite clays, acidified bentonite clays, and modified bentonite clays containing a flocculating agent. Generally speaking, the filter can be adapted to provide at least a 40 percent reduction in the caffeine concentration for about 1 cup to about 40 cups of a liquid.
