Biologically produced iron sulphide (FeS) is of great interest in the area of bioremedation as it posses adsorbing properties surpassing those produced by chemical means.

An optimum Fe(II):Fe(III) ratio is determined to maximise the magnetic susceptibility of the microbial sulphide produced. This will result in a reduction of the magnetic field intensity used in magnetically separating heavy metals in hioremediation applications.

Abstract

Biologically produced iron sulphide (FeS) is of great interest in the area of bioremedation as it posses adsorbing properties surpassing those produced by chemical means. This paper reports on the effect of varying the relative concentrations of Fe(II) and Fe(III) sulphates in the culture medium of a sulphate reducing bacteria chemostat on the magnetic properties of the iron sulphide produced. An optimum Fe(II):Fe(III) ratio is determined to maximise the magnetic susceptibility of the microbial sulphide produced. This will result in a reduction of the magnetic field intensity used in magnetically separating heavy metals in hioremediation applications. The paper details the economics of the separation and proposes a magnetically and cost optimised process for such applications.
