Chlorine is mostly used in the world to clean water and prevent water-borne infections. Chlorine is used in the production of plastics, solvents, polymers, medical pesticides, pesticides, pesticides and many other substances. Most drugs contain chlorine. Chlorine is also used in the production of polyvinyl chloride (PVC), which is used frequently in daily life. Today, chlorine chemistry is used in all areas of modern life.

Chlorine has an important place as bleach in house and environment cleaning.

Chlorine-based disinfectants are commonly used disinfectants. They show very fast bactericidal effect. The disinfectant effect may be low, medium or high depending on the dilution rate and contact time. The activity of chlorine compounds increases depending on concentration and temperature.

Chlorine-based disinfectant analyzes are also performed in authorized laboratories within the scope of physical and chemical analyzes of disinfectants. These laboratories use world-accepted test methods and test criteria in their studies and are based on standards issued by local and foreign organizations.

A few standards considered in chlorine-based disinfectant analyzes are:

• TS 5155 Laundry detergents (industrial)

This standard covers low foaming additive powder detergents used in industrial washing machines. The sodium chloride content in the laundry detergent is also determined.

• TS 54 Soap

This standard covers cleaning agents whose basis is soap. Sodium chloride content in the soap is also determined.
