The brine is composed of sodium cation (Na) and hypochlorite anion (OCl). Javal water is not explosive when it crystallizes and is stable if kept in the refrigerator. Javel water (sodium hypochlorite) is a pale greenish yellow dilute solution and its diluted solution is used as a bleach (Vitex). Javal water has other names such as antiformin , sodium chloride oxide, Vitex and bleaching liquid . In fact, the whitening liquid or household Vitex, which is usually used in all of our homes, has a concentration of 5% of saliva, and a concentration of 10% or more is called industrial Vitex.
Salt water or sodium hypochlorite (NaOCl) is one of the most widely used chemicals for disinfection and disinfection in various industrial and domestic applications. one of the important applications of Javal water in water and wastewater treatment It is . Javal juice has a spicy smell and taste, and its entry into the human body is very dangerous. Due to the presence of chlorine in this chemical, which is a volatile substance and decomposes with increasing temperature, you must store the juice in closed and opaque containers. Javal water is an unstable alkaline solution, in which chlorine gas evaporates at a rate of 0.75 grams. Therefore, Javal water is a strong corrosive and oxidizing solution and its 5% type has a pH of 11.
Various methods of producing juice
Sodium hypochlorite (javal water) is produced using the following two methods:
1- Production of javel water by injecting chlorine gas into caustic soda: with the introduction of chlorine gas into caustic soda , javel water is produced, for this, make sure that all tanks and pipes must be made of PVC, because metal tanks and pipes They corrode in the vicinity of chlorine gas.
NaOH+Cl—>NaClO+NaCl+H2o
The profit is poured into the tank and chlorine gas is introduced from the bottom. The desire to combine chlorine gas with profit is high, and after the combination of chlorine gas, it reaches the surface of the tank and is absorbed. Therefore, in this reaction, the lower the output of chlorine gas from the tank surface, the better the reaction of producing brine water is performed. The temperature of this reaction should not exceed 42 degrees Celsius.
2- Production of javel water by electrolysis of NaCl solution: in this method, to produce javel water electrolysis of sodium chloride solution is used . Electrolytic cells are used in cases of high current and neutral solutions.
What are the characteristics of Javal water?
Javal water is used as a chemical for disinfection and disinfection in various applications, including water and wastewater treatment. The chemical characteristics of Javal water are given in the table below.
| Molecular weight | 74.442 g/mol |
| density | 1.11 grams per cubic centimeter |
| melting point | 18 degrees Celsius |
| Boiling point | 101 degrees Celsius |
| Appearance | Pale green and clear yellow liquid |
| Purity | 14 to 15% |
| PKA (power of matter) | 7 |
| PH | Around 11 |
| Solution | in the water |
| b | Harsh and nasty |
Javal water has the following characteristics:
• Javal juice is unstable in contact with light and heat and should be kept in closed and opaque containers.
• It has high oxidizing properties and causes eye and skin irritation.
• High corrosive power
• Mixing the juice with other chemicals such as ammonia produces toxic gas chloramine, which is very dangerous.
• The use of Javal water in closed environments causes disturbances in the respiratory system and can cause more acute problems.
Applications of brine (NaOCl)
about many positive and negative features of Javal water Up to this point in the article , we have learned . Now we want to see what uses this chemical has; The most important applications of Javal water include the following:
Application of Javal water for water purification
In different water sources, there are all kinds of bacteria, fungi and microorganisms, which are very harmful to human health. This is the reason that after physical and biological water purification, part of the purification process is done using chemicals. Javal water is one of the chemical substances to eliminate water pollution, which used to disinfect water. as an antiseptic in water purification, which has been tried to be used less in recent years due to its limitations. Of course, chlorine can also be mentioned
Application of Javal water in wastewater treatment
One of the applications of Javal water is in industrial wastewater treatment. Releasing industrial wastewater in the environment without treatment causes serious damage to plant and animal species, for this reason, before entering industrial wastewater, we must bring it to the desired quality using disinfectants. Of course, various methods are used to remove pollutants in wastewater, such as manual and mechanical garbage collectors to remove suspended substances in wastewater, or biological methods, which are used to purify wastewater and bring it to an optimal level of quality. Involved.
Using Javal water for wastewater treatment causes its sodium hypochlorite to react with the cyanide ions in the wastewater and oxidize them. During this reaction, cyanide is converted into cyanate, which is less toxic. Therefore, it can be concluded, Javal water is used for disinfection of cyanide wastewater. For a better and faster reaction of brine with cyanide, the pH level is very important, because this reaction is faster at pH values higher than 10.
Application of Javal water in swimming pool water purification
One of the chemicals that can be used to purify and disinfect pool water is the use of chlorination. But due to the explosive nature of chlorine gas, in recent years, Javal water has been used for this purpose. By entering the pool water, Javal water removes pollutants and does not harm the skin. in disinfecting pool water with javel water PH is also very important , because this substance has a great effect on increasing the pH value. Therefore, it is recommended to measure the pH value in all stages of purification and disinfection of pool water with salt water.
Other common uses of Javal water include the following:
1- Removing stains on fabric
2- Eliminate the smell
3- Whitening and disinfecting surfaces
4- As a disinfectant in dairy industries, water tanks, laboratories, hospitals, etc.
5- Preventing the growth of algae and fungi in cooling towers
6- Dentistry for tooth root disinfection
7- Food industry, glass making, paper making, beverage and waste disposal
Safety tips for using Javal water
Javel juice is a poisonous substance and causes eye and skin irritation. Swallowing this chemical causes nausea, severe stomach pain, cough, diarrhea, lung problems and in some cases death. Javel water can become a dangerous substance due to its corrosiveness and availability. This chemical is not explosive, but it destroys the ozone layer.
If sodium hypochlorite (brine water) comes into contact with eyes or skin, flush the area with water for 15 to 20 minutes. In case of swallowing juice, immediately give the affected person milk or melted ice cream and see a doctor. Do not allow the juice to be exposed to direct sunlight or heated, as this solution is unstable and loses its properties.
Javal water can react with strong acids and react with metals such as iron, nickel and copper and cause combustion by producing oxygen gas. This chemical is non-flammable, but decomposes in heat and light and can cause an explosion under pressure.
Is Jawal water the same as Vitex?
Javal water is actually the same as Vitex and these two titles are not different from each other. Vitex or Javal water is used as an antiseptic or stain remover. The term that most of us call Vitex or bleaching liquid and it also has domestic uses is the concentration of 5% of Javal water, and what is known as Javal water among the common people is the industrial Javal water that has a concentration of 10 % . % of this chemical.
