Sulfates are raw materials in the form of crystalline powder. In fact, these are sulfate salts obtained as a result of the reaction of sulfuric acid. Therefore, they are called: magnesium sulfate, zinc sulfate, manganese sulfate, iron sulfate, copper sulfate.
As a rule, all salts of this group have a light shade, a certain degree of hardness, and many of them are perfectly soluble in an aqueous medium.
The main group is of sedimentary origin. For example, these are chemically identified marine sediments. The lion's share is mineral raw materials after oxidation.
Sulfates are known in scientific circles as volcanic foods (natural).
They can also be not only based on the reaction of sulfuric acid, but also aqueous, anhydrous. Difficult variants are distinguished, when a pair of anions (OH) is added to the [SO4] 2 complex.
Where can sulfates be found?
This is a natural component that is present in various parts of our planet. Any lake and river waters contain. “How do they get into the water?” You ask. Everything is quite simple when water passes through the layers of the earth in the form of rain (from the air, water takes particles formed as a result of the decomposition of sulfur oxide) and then enters the springs, which in turn form rivers. Then, on its way, it can meet gypsum, which, when washed out, gives a certain amount.
In industrial wastewater, the product may appear in several cases: 1. The enterprise uses directly raw materials additives based on sulphates. 2. In production, sulfur oxide is used, which, when oxidized, gives the desired substances. 3. The company uses additives for the manufacture of fertilizers.
The content of the substances in question does not affect a person. But the taste of the water changes due to the presence of such additives from the list below (the taste is palpable at a concentration of 300 - 400 milligrams per liter), therefore it is advisable to additionally purify the water, when used in food, with filters based on multilevel purification.
When mixing waters with different compositions, white deposits can appear on pipelines, taps and in the kettle itself during boiling.
How to check the concentration of anions?
For this, barium sulfate is taken as the main component and, depending on how much of it is obtained in a suspension (when diluted with water), you can find out the amount of anions. The turbidimetric method is used. Determination criteria: density, suspension column height, transparency. Also, for the analysis, you will need the most purified water and a turbidity meter. The device can be made by yourself.
What is the maximum permissible concentration level in reservoirs and natural reservoirs?
If we consider reservoirs intended for household and drinking nature, then the MPC is about 500 mg / l.
