Sodium hypochlorite (NaOCl) is the sodium salt of hypochlorous acid. Dissolved in water, it has a yellow-green, translucent, high pH color. It is characterized by a strong oxidizing effect. It is obtained by saturating the solution of sodium hydroxide and alkali metals with chlorine.
One of the basic uses of sodium hypochlorite is the treatment and improvement of drinking and technological water quality. According to the literature, sodium hypochlorite has disinfecting and bleaching properties. Due to these properties, it is widely used in water treatment in waterworks and in companies dealing with the supply of drinking water or having technological contact with food.
Sodium hypochlorite is commonly used for water treatment in swimming pools and water parks. It is used in home small tanks with a capacity of several cubic meters, as well as hotel and SPA installations as well as sports pools and amusement parks consuming hundreds of thousands of cubic meters of water a day. The recommended concentration for effective improvement of pool water is 200-250 ml of a 15% sodium hypochlorite solution for every 10,000 liters of water – at a water pH of 7.0 and a temperature in the range of 18-22 degrees Celsius. Also used as an ingredient in chlorine dioxide based water treatment installations.
Sodium hypochlorite due to its chemical properties is widely used in breeding poultry and other livestock. In the form of a 3% aqueous solution, sodium hypochlorite is an ideal disinfectant for breeding surfaces of poultry, pigs, horse cattle and cattle. This agent can be used on the surface as well as in the form of fog or spray. The product’s efficiency is estimated at about 300 liters of working liquid per breeding facility, e.g. a hen house with an area of 1750 to 2000 m2.
Sodium hypochlorite due to its biocidal properties confirmed in the literature is widely used in Western European countries as a measure in fruit trees and vineyards. Spring preventive spraying of fruit trees in a leafless state with a 3% aqueous solution of sodium hypochlorite – with a capacity of approx. 500 l per hectare of working liquid – is the recommended, common and planned care treatment in orchards and vineyards of the Netherlands, France and Germany. In publications of such authorities as Peter van Arkel, autumn spraying with three percent aqueous solution of sodium hypochlorite – with a capacity of approx. 500l of working liquid per hectare – is mentioned as very highly effective or highly effective in the prevention and control of cancer of fruit trees, especially Neonectria ditissima fungi also under the names Nectri galligena and Neonectria.
Sodium hypochlorite as a highly reactive oxidant with whitening and cleaning properties is widely used in the wood industry as a preventive and anti-blue wood agent. In order to prevent blue stain or remove discoloration, spraying or bathing in a 6-8% aqueous solution of sodium hypochlorite is commonly used.
