title: Studies on kinetics and thermodynamics of biomachining pure copper.
abstract: The kinetics and thermodynamics of biomachining pure copper by Thiobacillus ferrooxidans were quantitatively analyzed. The kinetic effect of bacteria on the ion-cycle between Fe(2+) and Fe(3+) and the thermodynamic effect of hydrolysis on the changes of pH in biomachining processes were expounded through six series of experiment. Finally a model of ion-cycle in the biomachining processes was proposed, and the measures for maintaining the stable equilibrium of the ion-cycle were also discussed.
