Our CatalyticCarbon Block Cartridges are Made in the USA and are of the highest grade, acid washed, ultra pure carbon infused with natural Zeolite to discourage bacterial growth, and exert strong catalytic activity for enhanced breakdown of chloramine, hydrogen sulfide and other difficult to remove chemicals. The carbon powder is compression molded into a block that yields 0.5 micron pores (that's apx. 50x smaller than beach sand), maximizing chemical adsorption and micro particulate filtration.
Activated carbon is effective at removal of the Radioactive Isotope Iodine-131 and various chemical contaminants such as Pharmaceuticals, Volatile Organic Compounds, Chlorine, Oil Industry Byproducts (petrochemicals), and more.
About Removing Radioactive Iodine 131 using Carbon:
[Activated carbon can be used as a substrate for the application of various chemicals to improve the adsorptive capacity for some inorganic (and problematic organic) compounds such as hydrogen sulfide (H2S), ammonia (NH3), formaldehyde (HCOH), radioisotopes iodine-131(131I) and mercury (Hg). This property is known as chemisorption.
Under an electron microscope, the high surface-area structures of activated carbon are revealed. Individual particles are intensely convoluted and display various kinds of porosity; there may be many areas where flat surfaces of graphite-like material run parallel to each other, separated by only a few nanometers or so. These micropores provide superb conditions for adsorption to occur, since adsorbing material can interact with many surfaces simultaneously. Tests of adsorption behaviour are usually done with nitrogen gas at 77 K under high vacuum, but in everyday terms activated carbon is perfectly capable of producing the equivalent, by adsorption from its environment, liquid water from steam at 100 °C and a pressure of 1/10,000 of an atmosphere.] - Wikipedia (source)
