A new simple and practical method for establish available chlorine

Nicol�������¡s Juan Carlos, Milanesio Romina Cintia

Disinfection is a necessary and obligatory procedure in the framework of good professional practice. In practical terms, it means eliminating microorganisms capable of producing disease through the use of a physical or chemical agent. The chlorine in the form of hypochlorite or bleach, is a powerful oxidant being disinfectant more important there because combines all the advantages required, including easy and cost convenient dosage.Available chlorine responsible for the bleaching and disinfecting functions, is defined as the oxidizing power of the chlorine content and is expressed in grams of available chlorine per liter (gCl2/L). Chlorine concentration tends to decrease over time, resulting determination important because it relates to the minimum dose recommended use to fulfill their function a parameter being evaluated in the accreditation and certification standards institutions. The recommendedmethod is the iodometric titration which is laborious and tedious. In this method the assay is performed for colorimetric automated by adaptation reagents routinely used in any clinical laboratory.
