			<abstract><p>Аннотация. Исследовано влияние составов борфтористоводородных электролитов на электрохимическую переработку отработанных свинцово–кислотных аккумуляторов. Показано, что, изменяя концентрацию свинцовой соли с 30 до 100 г/л, можно снизить уровень токсичности выбросов вредных веществ в окружающую среду при электрохимической утилизации отработанных батарей в 2 раза, а также повысить скорость переработки СКА в борфтористоводородных электролитах.</p>
<p>Предмет исследования: электрохимическая переработка отработанных свинцово-кислотных аккумуляторов.</p>
<p>Материалы и методы: экспериментальные исследования, основанные на определении допустимой плотности тока, скорости извлечения свинца, затрат энергии на его извлечение, выхода свинца по току, выбросов фторидов и свинца в атмосферный воздух, систематизация полученных данных.</p>
<p>Результаты: впервые изучена зависимость выбросов в атмосферу соединений фтора и свинца от состава электролитов для переработки СКА на основе борфтористоводородной кислоты.</p>
<p>Выводы: увеличение концентрации соли свинца в предлагаемом составе борфтористоводородного электролита уменьшает выделение удельных выбросов фторидов и свинца на тонну выделенного свинца в 2,2 раза по сравнению с ранее известным электролитом за счет увеличения скорости процесса переработки СКА в 2 раза. Электролит с повышенной концентрацией солей свинца дает меньшие концентрации токсичных веществ в 2 раза на границе СЗЗ (1000 м). При таком объеме производства (20 тыс. т) концентрации фторидов и свинца, выделяющиеся с поверхности электролитов, не превышают экологические нормативы, что говорит о возможности применения обоих составов электролитов на практике.</p>

<p>Annotation. The effect of the compositions of hydrofluoride electrolytes on the electrochemical processing of used lead-acid batteries has been studied. It is shown that by changing the concentration of lead salt from 30 to 100 g / l, it is possible to reduce the toxicity level of emissions of harmful substances into the environment during the electrochemical disposal of used batteries by 2 times, and also to increase the rate of processing of SCA in hydrofluoric electrolytes.</p>
<p>Subject of research: electrochemical processing of used lead-acid batteries.</p>
<p>Materials and methods: experimental studies based on the determination of the permissible current density, the rate of lead extraction, the energy consumption for its extraction, the current yield of lead, the emissions of fluorides and lead into the atmospheric air, the systematization of the data obtained.</p>
<p>Results: for the first time the dependence of emissions of fluorine and lead compounds into the atmosphere on the composition of electrolytes for the processing of SCA based on hydrofluoric acid was studied.</p>
<p>Conclusions: an increase in the concentration of lead salt in the proposed composition of hydrofluoride electrolyte reduces the release of specific emissions of fluorides and lead per ton of lead released by 2.2 times as compared to the previously known electrolyte due to an increase in the rate of the SCA processing process by 2 times. An electrolyte with an increased concentration of lead salts gives 2 times lower concentrations of toxic substances at the border of the SPZ (1000 m). With such a production volume (20 thousand tons), the concentrations of fluorides and lead emitted from the surface of electrolytes do not exceed environmental standards, which indicates the possibility of using both electrolyte compositions in practice.</p></trans-abstract><kwd-group xml:lang="en"><title>Keywords</title><kwd>lead-acid batteries</kwd><kwd>disposal</kwd><kwd>hydrofluoride electrolyte</kwd><kwd>emissions</kwd></kwd-group><kwd-group xml:lang="ru"><title>Ключевые слова</title><kwd>свинцово-кислотные аккумуляторы</kwd><kwd>утилизация</kwd><kwd>борфтористоводородный электролит</kwd><kwd>скорость</kwd><kwd>выбросы</kwd></kwd-group><counts><page-count count="8"/></counts>
