What is the role of activated charcoal in avoiding contamination?

∙ 15y ago
Activated carbon is often used in water purification. It reduces VOC's (volatile organic chemicals). Solid carbon blocks reduce even more percentages than granular or powered activated charcoal. It also gets rid of bad taste in water i.e. chlorine or iodine. It is used as an ancillary to chemical treatments of the water with bad tasting chemicals as well as highly reduces the presence of those chemicals such as chlorine or iodine. These chemicals kill the viruses and most bacteria and protozoa that can lead to water borne diseases.

∙ 14y agoThe purpose is to be an immediate interdiction in the event of toxic overdose when the substance was taken orally. The coal has been subjected to a process the gives the tiny granules a very vast expanse of surface area/binding sites. The idea is that the drug, which is not yet introduced into the bloodstream can be mitigated by having the charcoal bind and deactivate the overdosed / toxic / offending agent. It is often highly effective but timing is crucial. NEVER administer activated charcoal to someone who has taken a CNS depressant as they may aspirate after emesis (inhale their puke while passed out and suffocate or suffer acidic damage to the lungs). If the airway is not secured after administration of a cns depressant on toxic amounts then coal is contraindicated. An anti-emetic may reduce the danger by way of preventing puking but it will likely also increase the level of cns depression. Coal administration is extremely useful for pets however. If you suspect a pet of consuming household medications then preventative administration of the coal can save hundreds of dollars and your animal's life. I have just used 260 mg of coal to counter 12 mg of alprazolam and I can still write out the Krebs' cycle.... Its been 3 hours too. I'd say its effective. But then again I would not do such silly things as this. Do them again that is.

What is the role of Tris-HCl in phage preparation by PEG precipitation?
To Prevent Possible protease contamination
What is the role of cAMP in the signal transduction pathway activated by epinephrine?
It binds to and activates protein kinase A, which then phosphorylates other enzymes.
What is the role of G protein-coupled receptor?
To accept the ligand that properly fits the receptor sit. Then the G protein is activated and GDP is phosphorylated to GTP and the protein goes on to begin signal transduction in one of several ways open to G proteins.
What is the role of MgCl2 in plant protein extraction?
Function of MgCl2 in Protein Extraction Our work shows that MgCl2 in osmotic shock buffer at a concentration of 2 mM improves protein extraction and reduces contamination with other proteins. To achieve a simplified purification procedure for rhGM-CSF, work focused on adjusting the pH of the buffer and applying the correct salt concentration.

Can the RI National Guard be legally deployed to assist in a drug raid?
Yes. When activated by the state government, they may be tasked for law enforcement purposes. However, they may not perform in this role when federally activated, unless the Insurrection Act is in effect.
What is the role of charcoal in gunpowder mixture and why not ashes because I think ashes would provide more carbon than charcoal?
No - simple ashes contains more than just carbon. It contains other elements from burning wood - such as sap, insect bodies etc. Charcoal is pure carbon - all other 'additives' are burned off during the manufacturing process.

How much does a charcoal grill cost at a yard sale?
Yeah I would be fine. But it also depends on the condition of your grill. Even if it is new lot of other factors like brand and the availability of spare parts also plays a major role.
