Clays are particularly known for their ability to remove toxic metals from the air, water, and soil because of their unusual structure of “pores” (channels and holes) that allows them to absorb huge amounts of contaminant materials. Toxic gases, chemicals, mold, heavy metals, and other toxins are drawn by the natural negative electrical charge into the crystal micro pores of the clay. The unique structure of clay provides literally millions of pores or sieves - “shape-selective catalysts” - that catch only molecules small enough to fir into the cavities while excluding larger molecules. The unique structure of clays therefore gives them unusual filtering capabilities for absorbing toxic wastes, including radioactive contaminants. In just one gram of Zeolite clay, for instance, the three dimensional structure of the channels in its crystalline structure provide up to several hundred square meters of surface area on which absorption (and channel reactions) can take place. The Zeolites are particularly useful for removing heavy metals and radioactive species from water.
