Determination of Active Chlorine and Sodium Hypochlorite

Determination of Active Chlorine and Sodium Hypochlorite

Sodium hypochlorite is a chemical compound that is effectively used for the purification of water. Common uses are surface cleaning, bleaching, deodorization and water disinfection. It was first discovered in the late eighteenth century and was originally used to bleach cotton. Hypochlorite can remove stains from laundry at room temperature. Sodium hypochlorite solution is a weak base that is flammable. A pH of 11 is irritating and a pH of 13 is corrosive.

Determination of Active Chlorine and Sodium Hypochlorite

Sodium hypochlorite is primarily used in agriculture, chemicals, paints and lime, food, glass, paper, pharmaceuticals, synthetics, and waste disposal industries. For example, in the textile industry, sodium hypochlorite is used to bleach textile products. It is sometimes added to industrial wastewater to reduce odors. In water treatment, it is used to disinfect water. Hypochlorite is frequently used for cleaning and disinfection purposes in homes and offices. Sodium hypochlorite is highly effective against bacteria, viruses, and fungi.

Hypochloric acid, also known as active chlorine, is formed in a solution obtained by electrolyzing water and salt. Active chlorine is an effective disinfectant or antiseptic that kills bacteria and viruses. The disinfection effect of chlorine in water depends on the following factors: the amount of active chlorine, the pH of the water, the water temperature, and the contact time of free chlorine with microorganisms in the water.

In the test, analysis, measurement and evaluation studies carried out in our organization, national and international standards and applicable legal regulations are complied with and reliable and impartial results are obtained. Among the numerous tests performed in this context, there are also services for the determination of active chlorine and sodium hypochlorite.
