What is sulfur?
(in English: Sulfur) is placed in the periodic table on the left side of chlorine, below oxygen and above selenium, and its chemical symbol is S and its atomic number is 16. The discovery of this element goes back to prehistoric times. Therefore
It is a smelly, foul-tasting and polyvalent non-metal that is mostly available in the form of yellow crystals. Flea killer is useful for fertilizer and agriculture. This element is primarily used in fertilizers; But it is also widely used in gunpowder, softeners, matches and insecticides.
Sulfur mineral resources
The sulfur element is present in many deposits in the form of various compounds:
Free sulfur deposits:
They are found in nature and are divided into four groups based on their origin:
Deposits of biological origin: bacteria play an essential role in their formation and they are mostly sedimentary. Therefore
Deposits of volcanic origin: in the vicinity of bubbling springs, in sky rocks as well as volcanoes and volcanic cones or as sulfur veins inside volcanic rocks.
Sulfide deposits:
Deposits of iron sulfides: a combination with other elements is found in the form of sulfides such as pyrite. Sulfur in these deposits is obtained from iron minerals along with pyrite and pyrrhotite. Sulfur is also found in layered iron deposit deposits that have sulfide zone.
Deposits of non-ferrous metal sulfide : recovery of sulfur along with sulfide minerals such as sphalerite
Sulfate deposits:
They are one of the most widespread sources of sulfur and sulfur is found in this deposit along with minerals such as gypsum, anhydrite and barium sulfate.
Tar and oil sands:
It exists as an organic complex in tar and oil sands and is obtained as a by-product during their refining.
Coal and oil shale:
The sulfur element is produced in small amounts as sulfur dioxide when burning coal and oil.
Oceans:
It is found as soluble sulfates of calcium, magnesium and potassium in ocean water.
Biological role
Amino acids cysteine, methionine, homocysteine, taurine and also some enzymes contain sulfur. About 0.25% of human body weight is sulfur. Sulfur is present in keratin, which is the structure of hair and nails. Also, disulfide compounds between polypeptides are very important in protein structure. Sulfuric compounds cause bad breath.
Applications of sulfur
1) Application in the production of chemicals:
For the production of sulfuric acid and synthetic fibers, dyes and pigments, matches, explosives, including gunpowder, hydrogen sulfide, sulfur trioxide and thionyl chloride, which is used as a reagent in chemistry, carbon disulfide, an important organic solvent. Therefore
2) Application of sulfur in agriculture:
It is an essential participant in photosynthesis and plant respiration processes. As a component of some vitamins, it has a positive effect on the fixation and absorption of nitrogen from the atmosphere and trace elements by plants.
Its role in improving the flavor and aromatic characteristics of plants such as onions or garlic should be mentioned. As well as increasing the resistance of products against diseases and pests
In the form of sulfuric acid to phosphatize fertilizers, magnesium sulfate in plant nutrition
As a nutrient (sulfur fertilizer):
It is an essential plant element such as nitrogen, potassium and phosphorus. In addition to its nutritional properties, it improves the soil and helps to fix nitrogen and phosphorus. Intensive agriculture around the world has led to a lack of sulfur in the soil. Actions to stop air pollution by reducing or eliminating sulfur dioxide emissions from power plants have reduced the uptake of sulfur by soil. Therefore
Using the properties of sulfur as a pesticide:
It is one of the oldest known pesticides. Its best use is for vegetables and fruits. Controls psyllium, spider mites and thrips but is toxic to cucumbers, raspberries and apricots. Sulfur powder cannot be mixed with horticultural oils and used as a pesticide on plants, because this combination causes the plants to die. Therefore
As a fungicide:
Controls powdery mildew and fungus on leaves. It works best when applied to dry leaves. Sulfur prevents mold growth and should be
applied before the fungus settles. Re-rain is
required after heavy rainfall. Therefore Sulfur stops cuttings from succulent plants such as begonias from rotting. The stem is
dipped in sulfur before propagation. It also prevents mold from forming on bulbs and rhizomes. The downside is that it can burn the leaves at temperatures above 90 degrees Fahrenheit. Therefore
As a soil pH reducer:
Most plants prefer soils with a pH range of 5.8 to 7.0. Therefore Some plants like azaleas, gardenias and blueberries prefer acidic soil. Soils in limestone areas may have a pH of 8.0 and consist of 50% lime. Such alkaline soils cause iron, zinc and manganese deficiency. In this situation, leafy plants may turn yellow. A sulfate-based fertilizer may solve these problems, but in more severe cases, powdered elemental sulfur is
needed. Therefore
3) Application of sulfur in rubber making:
In rubber making, this element is of special importance for the vulcanization of black rubber. Therefore
4) in road construction:
To obtain asphalt and asphalt concrete, calcium sulfate (gypsum) on a scale of 100 million tons annually for use in cement and gypsum
5) In pulp and paper:
Sodium bisulfite for paper production, paper bleaching
6) Application of sulfur properties in fabric production:
This widely used element is
used in the textile industry to whiten fabrics. Therefore
7) Application of sulfur in food industry:
In the food industry, it is
used as a preservative in the form of sulfite in the production of sugar. Therefore
8) Application of sulfur in medicine:
For the production of many medicinal products, the treatment of some skin diseases, Epsom salts (magnesium sulfate), which are
used as laxatives, exfoliants
9) Application of sulfur properties in detergents:
Many surfactants and industrial detergents are sulfate derivatives. Therefore Sulfur dioxide is
used as a bleach and disinfectant.
10) mercaptans:
are a family of organosulfur compounds. Therefore Some are
added to natural gas sources because of their distinctive smell, so gas leaks are easy to detect. Others are
used in silver polishing
11) Magnesium sulfate for bath additive
Other uses:
Fungal killer as well as disinfectant and fertilizer
gunpowder production
Its application in rubber welding
Production of sulfuric acid
It is used to make several types of paper, as a bleaching agent and as an electrical insulator
Production of sulfuric acid (H2SO4) for batteries
Making matches and fireworks
Ammonium or sodium thiosulfate as a fixing agent in photography
Magnesium sulfate as an anti-drying and laxative agent, which is a herbal magnesium supplement
Beauty and cosmetics
Physical and chemical properties
Sulfur (S), a non-metallic chemical element belonging to the oxygen group (group 16 of the periodic table), is one of the most reactive elements. Pure sulfur is a poor conductor of electricity and insoluble in water.
chemical properties
There are characteristics that determine how it reacts with other substances or changes from one substance to another. The better we know the nature of matter, the better we can understand it. Therefore Chemical properties can only be
observed in a chemical reaction. Reaction to materials may be
caused by changes due to burning, rusting, heating, explosion, staining, etc.
