摘要：

The possibility of using a carbonate-containing technogenic waste as reagent for treatment of aqueous solutions to remove lead(II) ions is demonstrated. The economical and environmental advantages of this treatment procedure compared to the procedure with traditional sorbents are noted. The influence of the concentrations of the initial solutions, amount of the reagent used, and treatment time and temperature on the degree of recovery of lead(II) ions is examined. The optimum conditions of wastewater treatment to remove lead(II) ions to the maximum permissible concentration level are chosen. The spent reagent contains up to 7 wt % lead and is a promising raw material for producing lead metal.
