摘要：

The extraction of zinc(II) ions with DX-510A β-diketone from sulfate and ammonia–sulfate solutions is reported. The effects of the aqueous phase pH and extracting agent concentration on the process have been investigated. The highest zinc(II) ion recovery is observed at pH 8.5–9.0. The time to extraction equilibrium is no longer than 30 s; in back extraction, it does not exceed 70 s. The extraction of zinc(II) ions is accompanied by the formation of an ammonia-containing organic complex. A chemical formula is suggested for this compound.
