Research project: Study of the equilibrium and kinetics of mercury sorption and desorption by power station fly ash and assessment of the role of ash in limiting the bio-availability of mercury

Currently Active: 

A project funded by the INTAS Programme

It is known that power station fly ash can act as a sorbent for mercury in aqueous solutions, and that it appears to bind strongly to mercury in soil. Fly ash itself is a multi-component system, composed of glass, amorphous, crystalline and carbon phases. In addition, mercury appears in many forms, varying significantly in their stability and the degree of threat posed to human health and the environment. The overall behaviour of the ash-mercury system is thus extremely complex, and may involve both physical and chemical bonding, precipitation and entrapment.
