Description

Недостатка-ми примен емых в пасто шее врем  свинцовых электролитов  вл етс  сложность приготовлени ,  довитые и агрессивные свойства, склонность к гидролитическому распаду и т. д.The drawbacks of lead electrolytes used in pasta are the difficulty of preparation, poisonous and aggressive properties, tendency to hydrolytic decomposition, etc.

Предлагаемый электролитический способ получени  свинца из азотнокислых растворов исключает указанные недостатки и позвол ет получить на катоде плотные свинцовые осадки.The proposed electrolytic method for producing lead from nitric acid solutions eliminates these drawbacks and makes it possible to obtain dense lead precipitates at the cathode.

Подвергаемые электролизу исходные растворы содержат 50-75 г/л свинца и 5 г/л азотной кислоты. Качество катодного осадка свинца резко улучшаетс  при введении в раствор комбинированных добавок (в г/уг): 1-1,6 кле , 0,2-0,5-а-нитрозо-р-нафтола и 0,3-0,5 резорцина.Subjected to the electrolysis of the original solutions contain 50-75 g / l of lead and 5 g / l of nitric acid. The quality of the cathode lead sediment improves dramatically when combined additives are added to the solution (in g / ug): 1-1.6 glue, 0.2-0.5-a-nitroso-p-naphthol and 0.3-0.5 resorcinol .

Электролиз проводитс  при плотности тока на катоде 100- 150 aJM в течение 24 час при 20-30°. В рфзльтате получаютс  плотные , мелкокристаллические свинцовые осадки с блест щей поверхностью . Катодный выход свинца по току равен 98-99%. Концентраци  а-нитрозо-р-нафтола должна быть тем больше, чем больше цримеи ема  плотиость тока.Electrolysis is carried out at a current density at the cathode of 100-150 aJM for 24 hours at 20-30 °. In crystallization, dense, fine crystalline lead precipitates with a shiny surface are obtained. The cathode output of lead current is 98-99%. The concentration of α-nitroso-p-naphthol should be the greater, the greater the application density of current.

Катоды из листового свинца предварительно обезжириваютс  и протравливаютс ; аноды отливаютс  цз свинца марки С-О.Lead cathodes are pre-degreased and pickled; the anodes are molded with CS of lead.

Пред м ет изобретени Present Invention

Электролитический способ получени  свинца из азотнокис.пых растворов с добавкой органических веществ, отличающийс  тем, что, с целью получени  плотных свинцовых осадков, электролизу подвергают исходные азотнокислые растворы, содержапше 50-75 г/л свинца, 5 г/л азотной кислоты с добавками: 1 -1,5 г/л кле , 0,2- 0,5 г/л а-нитрозо-р-нафтола и 0,3-0,5 г/л резорцина.The electrolytic method of obtaining lead from nitric oxide solutions with the addition of organic substances, characterized in that, in order to obtain dense lead precipitates, the initial nitrate solutions, containing 50-75 g / l of lead, 5 g / l of nitric acid with additives are subjected to 1 -1.5 g / l glue, 0.2-0.5 g / l a-nitroso-p-naphthol and 0.3-0.5 g / l resorcin.
