Применение хлорсодержащих реагентов для обеззараживания воды в плавательных бассейнах может приводить к образованию хлораминов, ухудшающих органолептические свойства воды и влияющих на здоровье пловцов. Для снижения содержания хлораминов в воде бассейнов может применяться ультрафиолетовое излучение.</p></sec><sec><title>Цель работы</title><p>Цель работы. Изучение влияния УФ-излучения на трансформацию моно- и дихлораминов в воде.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Исследование проводилось на пробах воды из детских бассейнов, а также в модельном эксперименте на аквариумной воде с внесённым гипохлоритом натрия. Пробы подвергали обработке ультрафиолетовым излучением с дозами 40, 80 и 120 мДж/см2. До и после УФ-обработки во всех пробах было определено содержание хлораминов.</p></sec><sec><title>Результаты</title><p>Результаты. В результате работы было выявлено, что доза ультрафиолетового излучения 40 мДж/см2 является недостаточной для разрушения моно- и дихлорамина в воде. При обработке проб воды УФ-излучением с дозой 80 мДж/см2 наблюдалось снижение содержания монохлораминов и увеличение содержания дихлораминов, зависящее от исходной концентрации активного хлора.</p></sec><sec><title>Заключение</title><p>Заключение. Таким образом, эффективной дозой ультрафиолетового излучения для снижения концентрации монохлораминов в воде при концентрации активного хлора 0,5 мг/л является 80 мДж/см2. Однако стандартное УФ-оборудование, применяемое для обеззараживания воды бассейнов, не может гарантировать снижения концентрации хлораминов, так как обычно оно рассчитано на минимальные требуемые нормативами дозы УФ-излучения (25–40 мДж/см2). Кроме того, воздействие УФ с дозой 80 мДж/см2 на воду с повышенным содержанием активного хлора приводило к значимому увеличению содержания дихлораминов, что предположительно связано с разрушением белков в воде под влиянием УФ-излучения и последующей реакцией аминокислот с активным хлором.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. The use of chlorine-containing reagents for disinfection of water in swimming pools may lead to the formation of chloramines, both worsening the organoleptic properties of water and affecting the health of swimmers. To reduce the content of chloramines in pool water, UV radiation can be used. </p><p>The aim of work is investigation of the effect of UV radiation on the transformation of mono- and dichloramines in water.</p></sec><sec><title>Material and methods</title><p>Material and methods. The study was conducted on water samples from children’s pools, as well as in a model experiment on aquarium water with sodium hypochlorite added. Samples were irradiated with ultraviolet at doses of 40, 80 and 120 mJ/cm2. Before and after UV treatment, the content of chloramines was determined in all samples.</p></sec><sec><title>Results</title><p>Results. UV dose 40 mJ/cm2 was found to be insufficient for the destruction of mono- and dichloramine in water. During UV treatment with a dose 80 mJ/cm2 a decrease in the content of monochloramines and an increase in the content of dichloramines were observed. These processes were depended on the initial concentration of active chlorine in the samples.</p></sec><sec><title>Conclusion</title><p>Conclusion. Thus, an effective UV dose to reduce the concentration of monochloramines in water with a concentration of active chlorine of 0.5 mg/l is 80 mJ/cm2. However, standard UV equipment used for disinfection of pool water cannot guarantee a reduction of chloramine concentration as it is usually designed for the minimum required UV dose (25-40 mJ/cm2). In addition, the effect of UV at this dose on water with a high content of active chlorine led to a significant increase in the content of dichloramines, which is supposedly associated with the destruction of proteins in water under the influence of UV radiation and the subsequent reaction of amino acids with active chlorine.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>хлорамины</kwd><kwd>плавательные бассейны</kwd><kwd>ультрафиолетовая обработка</kwd><kwd>трансформация веществ</kwd><kwd>обеззараживание воды</kwd><kwd>свободный и связанный хлор</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chloramines</kwd><kwd>swimming pools</kwd><kwd>UV-treatment</kwd><kwd>transformation of substances</kwd><kwd>water disinfection</kwd><kwd>free and bound residual chlorine</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Мифтахова К.Р., Пьянкова О.Г., Рудакова Л.В., Глушанкова И.С.
