Activated carbon or activated charcoal is here are a range of different activated charcoals, but only pharmaceutical grade powdered activated charcoal is suitable for use in clinical toxicology. Granular, extruded, or beaded activated charcoals are considerably less porous and are not suitable for use for adsorbing xenobiotics, and the same is true of activated charcoal biscuits, tablets, or capsules. The binding capacity of activated charcoal is usually expressed as iodine number, which is the number of milligrams of iodine bound by one gram of activated charcoal. Pharmaceutical grade activated charcoal has an iodine number in the range of 600–1100 mg/g.
now the activated carbon is very powrful in medicine and pharmacy and water treatment ,How?
Hello Tareq Alasadi
Activated carbon has a high surface area (BET). This may be a fundamental reason for its versatile use as an adsorbent.

Dear Arnab ,good idea ,activated carbon is very good in many applications .,as you said .,cheap raw material and valuable use .
Activated carbon is a medication used to treat poisonings that occurred usually by mouth. but to be effective it should be used within typically an hour. The body is unable to absorb charcoal, and so the toxins that bind to the charcoal leave the body in the feces.
also, people have long used activated carbon as a natural water filter. Activated carbon is considered as one of the most effective adsorbents because of high chemical and thermal stability, high porosity, high sorption capacity and having an immense surface area. Granular activated carbon is commonly used to adsorb natural organic compounds, taste and odor compounds, and synthetic organic chemicals in drinking water treatment.
Dear perera ,excellent reply ,activated carbon is used in canister to absorb many chemical agents ,like nervous gases ,still used to intoxicate dangerous gases,
