Beschreibung
Zusammenfassung:	FIELD: chemistry.SUBSTANCE: method involves electrochemical deposition of lead from alkaline solutions on asymmetric pulsed current with variation of the periodic sequence of packets of positive n+ and negative n- current pulses, wherein the number of pulses in a packet is selected from n+=20 and the interval 1?n-?10.EFFECT: high degree of extraction of lead from alkaline solutions, low costs, environmental safety and wasteless production.4 ex Изобретение относится к способу извлечения свинца из отходов аккумуляторных батарей. Способ включает электролитическое осаждение свинца из щелочных растворов на асимметричном импульсном токе с варьированием периодической последовательности пакетов положительных n+ и отрицательных n- импульсов тока, причем количество импульсов в пакете выбирают из n+=20 и интервала 1≤n-≤10. Обеспечивается повышение степени извлечения свинца из щелочных растворов, снижение экономических затрат, экологическая безопасность и возможность безотходного производства. 4 пр.
