Abstract
Process of extraction of Pb2+ ions from aqueous media with a composite sulfur-containing precipitating agent based on iron and sulfur powders at an iron: sulfur mass ratio of 100: 1. The optimal modes of its effective and ecologically safe use were determined. Addition of a thermally expanded graphite to the sulfur-containing precipitating agent makes lower the temperature of maximum recovery lead(II).
