Poison
Molecular formula :
CAS :

nature : (a) toxicant right organisms harmful effects of the substances. Chemical substances (including drugs, poisons or pesticides, etc.) as toxic dose is the key, which emphasized a chemical poisoning if it reaches dose is toxic. Only those actually more dangerous, a small amount of exposure can be toxic substances, known as poison. On drugs, small doses produce therapeutic effects, and high-dose (overdose) produce toxic effects, it can become toxic. Only in a small can cause poisoning substances, toxic said. (2) When a small amount of poison material accumulated on the surface of the catalyst, catalyst loss of catalytic activity, such material is difficult to remove from the catalyst surface, and thus the catalyst deactivation is not reversible, such as material on the catalyst poison. Toxicology mainly through chemical adsorption method and the surface active sites on the combination may also plug the porous catalyst, it will give a small amount of poison, would suffice to completely lose its catalyst activity. The ion exchange resin recycling process, the resin adsorption capacity is gradually declining. With some impurities in the normal operation can not be washed by the resin washed down and resin phase in the gradual accumulation. This is the resin poisoning, caused resin poisoning or ion compounds, namely, the toxic resin. The common silicon poisoning, molybdenum poisoning, and even more sulfate poisoning.
