1. A modified organic bactericidal mineral media, said media comprising:
- a mineral selected from the group consisting of clays and zeolites; and
an organic modifier selected from the group consisting of a quaternary ionic compound in combination with iodine or an iodine compound, or combinations thereof, wherein said organic modifier is present in an amount sufficient to achieve a reduction in bacteria present in aqueous media contacted by the mineral media for an interval of at least five minutes, the amount of bacteria present after five minute exposure being essentially zero.

Abstract
A bentonite based organoclay, when mixed with a biocidal quaternary amine containing a benzyl molecule within its structure, acts as a reasonably effective biocide.
When this organoclay is further treated with iodine and iodide compounds, its efficiency is greatly enhanced.
