Biological Recovery of Platinum Complexes from Diluted Aqueous Streams by Axenic Cultures

Table 1

An overview of the platinum recovery efficiencies (%) at pH 2 is given; the Pt recovery was investigated with and without (sorption control) the addition of H2-gas.

The platinum recovery was studied using five different bacterial species and five Pt-complexes (n = 1). All recoveries were measured after 48 h, except for: * 68 h, ** 107 h and *** 168 h, and **** 320 h. The chemical reduction was studied for all Pt-species using H2-gas.
