Research output: Chapter in Book/Report/Conference proceedingConference contribution


The remediation of metal-contaminated soils is a growing environmental problem. Current practice often involves either capping contaminated sites or removing contaminated material and storing it elsewhere. However, given that metal phosphates are highly insoluble under a wide range of Eh and pH conditions, it has been suggested that the conversion of metals into metal phosphates may represent a sustainable, in situ, remediation technique for metal-contaminated soils. In this chapter the solubility of metal phosphates and experimental work investigating the potential for metal phosphate formation as a remediation technique are reviewed. It is concluded that current work indicates that metal phosphate formation may well be a viable treatment. However, further held trials and investigations into the solubility of some less well known metal phosphates, particularly in the presence of organic ligands and microorganisms are required.
