Description

(54) СПОСОБ КОНЦЕНТРИРОВАНИЯ СВИНЦА (54) LEAD CONCENTRATION METHOD

Claims (2)

Формула изобретенияClaim 1. Способ концентрирования свинца экстракцией его органическим растворителем из кислых растворов,в присутствии иодид-ионов-и реагента, отличающийся тем, что, с целью повышения степени и селективности концентрирования, в качестве органического растворителя используют смесь хлороформа с петролейным эфиром, а в качестве,реагента - нонилдиантипирилметан.1. A method of concentrating lead by extraction with an organic solvent from acidic solutions in the presence of iodide ions and a reagent, characterized in that, in order to increase the degree and selectivity of concentration, a mixture of chloroform with petroleum ether is used as an organic solvent, and, as reagent - nonyldiantipyrylmethane. 2. Способ по п.1, о тли ч а ю щ и й с я · тем, что экстракцию осуществляют йз 1-6 н. серной кислоты, содержащей 0,6-1,5 М раствор иодида калия.2. The method according to claim 1, with the exception that extraction is carried out with 1-6 n. sulfuric acid containing a 0.6-1.5 M solution of potassium iodide.
