Chloric iron 2828900000
What is ferric chloride? This is a salt that is obtained as a result of the interaction of hydrochloric acid and iron and has the appearance of yellow-black pieces or soft crystals. The resulting mass melts at 309 degrees, and its boiling point is 319 degrees. There are also several other ways to obtain such a salt:
oxidation of a mixture of iron with perchloric acid, after which evaporation is carried out, as well as its formation as an additional product in the production of chlorine salts of aluminum or titanium.
Ferric chloride: how to use it and what for?
Most often, this salt is used as a coagulating agent for water purification.
If we compare it with other coagulants, then it has the main advantage - a high rate of precipitation of unnecessary impurities in water. That is why it is usually used in the treatment of waste and industrial waters in settlements. When combined with water, ferric chloride, the use of which is more desirable than, for example, aluminum sulphate, is formed practically insoluble iron hydroxide. It is a flake that can be easily removed from the effluent. In the process, any substances are removed from the water together with the flakes formed by interaction with ferric chloride.
The flakes obtained by combining water with ferric chloride are quite dense and are excellent sorbents. They capture any suspension - microorganisms, silt, plant parts, and so on, so their structure consists of the above-described material, colloidal particles and other substances. With the help of ferric chloride, everything settles much better and faster.
Moreover, this solution is economical - only 30 g of the mixture is needed per 1 cube of water. Soluble sludge is reduced by 25%, and insoluble - by 90-95%, that is, almost completely. For its complete destruction, sodium hypochlorite is used.
It should be noted that ferric chloride is also used as:
- process accelerator in the synthesis of organic substances;
- a component of mixtures for the manufacture of pigments based on iron-containing particles;
- stains for dyeing various fabrics;
- substances for the production of printed circuit boards.
Ferric chloride is also worth buying for acceleration of organic processes in the production of heat-resistant resins. It also participates in the selective extraction of some components of the ore, and with its help they oxidize petroleum bitumens. When combined with aromatic hydrocarbons, it participates in the electrophilic substitution reaction. It is also used in the form of aqueous solutions.
Ferric chloride is most actively used in the field of instrument making, in the production of electronics, in construction. This mixture accelerates the setting of cement and concrete mortars, and also contributes to greater strength of such structures.
Ferric chloride cleans not only waste water, but also the residual fat from the effluents of factories producing butter, margarine, mayonnaise, and so on. It cleans water for technical applications, and also removes chromium from the wastewater of factories that manufacture leather and fur products.
This solution is used in photography as a tinting component, as well as starting material for the production of other compounds with the participation of iron. It not only cleans, but also softens water for household needs. It is used to etch circuit boards in the manufacture of electronics, dye fabrics, accelerate the process of organic synthesis, and much more.
Wastewater treatment is required for any industrial enterprise, chemical processes also occur everywhere. And if we take into account the properties of ferric chloride,
