Solubility of Litharge (a-PbO) in Alkaline Media at Elevated Temperatures

PDF Version Also Available for Download.

Description

An inert, flowing autoclave facility is used to investigate the solubility behavior of {alpha}-PbO (litharge, tetragonal) in aqueous solutions of morpholine, ammonia and sodium hydroxide between 38 and 260 C. Lead solubilities increased from about 0.4 mmol kg{sup -1} at 38 C to about 4.5 mmol kg{sup -1} at 260 C and were relatively insensitive to the concentration and identity of the pH-reagent. The measured lead solubilities were interpreted using a Pb(II) ion hydroxocomplexing model and thermodynamic functions for these equilibria were obtained from a least-squares analysis of the data. A consistent set of thermodynamic properties for the species Pb(OH){sup ... continued below

A consistent set of thermodynamic properties for the species Pb(OH){sup +}, Pb(OH){sub 2}(aq) and Pb(OH){sub 3}{sup -} is provided to permit accurate lead oxide solubility calculations over broad ranges of temperature and alkalinity.
