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.
