What makes activated carbon: composition of tablets
Activated charcoal: varieties, method of action and composition of tablets
Ancient people noticed that if the wood in the firing process will not be in contact with fire, the charcoal better absorb all odors. Initially, in order to achieve the desired «activity», the coal was placed in a closed clay pot and thus was subjected to heat treatment. This activated charcoal called only when he learned to produce on an industrial scale. The name should be due to the activation process of the absorbent properties of such coal, when it becomes able to absorb extraneous molecules and compounds.
The composition of activated carbon has long been not included charcoal. This product is more adapted material: coconut shell, fruit, charcoal, silicone gel, and organic polymers. By special processing, this achieves a very high percentage of microcracks on the weight of the finished product. Thus, in manufacturing with special technology are making content more than 1000 pores per gram of coal. For comparison, in house conditions it is possible to obtain activated carbon with just a few tens of pores per gram of product.
Varieties of activated carbon
Ready-made activated carbon looks like granules with a size of about 1 mm. After production is also more fine dust, which, however, no less valuable, as it has the same absorbency. Granular coal is briquetted and pressed often for simplicity and ease of use. Powdered charcoal is often used for filters for purification of water. But the most popular variety forms of activated charcoal is charcoal tablets. The granules are compressed into tablets – they can also be crushed into powder for use in various purposes.
The meaning of the action of this medication is that processed at high temperature original raw material is converted into a porous charcoal with multiple microcracks, looking to fill my empty space of any materials of suitable size. Huge sorptive (absorptive) capacity of a product such as activated carbon and determines its effectiveness.
However, whether activated charcoal to cope with all the toxins and dangerous substances that are ingested or water filter? Used for making activated carbon, determines the size of the cracks and pores on its surface. If the cracks are less matter collided with a particle of coal will not be able to absorb. For example, some heavy metals, minerals and trace elements.
Composition of tablets of activated charcoal
«Activation» activated carbon, due to which it got its name, is that in the heat treatment process of the raw material at high temperatures does not occur to its contact with fire. The raw material is isolated directly from the flame or use electric heating methods.
Part of the tablets includes:
- activated carbon;
- «black salt».
This form is used in some food poisoning. It should be remembered that the properties of activated carbon are not only in the absorption of toxins, but it equally absorbs useful minerals. «Washed» in this case, primarily potassium, magnesium and calcium. Therefore, the presence of black salt is very useful for the body an additional source of these minerals. Not all tablets are produced with the same composition, and the presence of black salt should be clarified in information about the composition on the packaging. Found another pill, which consists of activated charcoal, starch and sugar.
Activated charcoal acts on the substances by binding to their active properties. It binds alkaloids, barbiturates and many other active substances, absorbing them and removing from the body naturally cleanse. Not has a sufficient adsorbing activity on acids and alkalis, and iron salts, cyanides, Malathion, methanol, ethylene glycol.
The drug is most effective when taken either before or immediately after the poisoning. Can be taken locally to ulcers and other injuries to speed healing.
The principle of operation activated carbon
In this article, we found that coal tends to fill many of their voids, which originated in its structure after treatment with high temperatures. Once the contaminated water or other fluid (for example, among the contents of the stomach or intestines), coal absorbs everything he can to stay in the cracks and pores. It should be remembered that if coal were not enough, its adsorbing action may be ineffective in the case where the number of sorbed substances exceeds the capacity to absorb them.
Food can also interfere in this process and its presence in the stomach should be accompanied with increasing doses, which is on average 1 tablet per 10 kg body weight – with a slight disorder. The main action of the coal, leading to his «activity» is the number of pores, which reaches its maximum size with proper treatment. Due to this porosity, the coal becomes weightless and one gram of coal is able to accommodate a thousand or more of pores and microcracks, which is achieved by using ultra-high temperatures.
Activated charcoal – a universal drug that has been used successfully for many years in medicine, chemical, pharmaceutical and food industries. Filters containing activated charcoal are used in many modern models of devices for purification of drinking water, as they are able to clear even from chlorine.
