The interactions of Co2+ with haematite are investigated as a function of the solution pH by means of acid-base titrations and direct adsorption measurements.

Abstract

The interactions of Co2+ with haematite are investigated as a function of the solution pH by means of acid-base titrations and direct adsorption measurements. Adsorption determinations show that Co2+ is adsorbed on haematite to increasing extents with increasing solution pH. The desorption of Co2+ from haematite is also found to be a function of pH as Co2+ can be desorbed on acidification of the solution; however, the adsorption is never fully reversible. From acid-base titrations the adsorption of Co2+ appears to modify the primary H+-OH- adsorption equilibria of the oxide surface. © 1983.
