Notes:
In this paper, we present results from SIMS, XPS and Fourier transform infrared photoacoustic spectroscopy (FTIR-PAS) in order to determine the nature of the phosphorus compounds produced by the reaction of POCl3 gas and chrysotile asbestos. SIMS ion images show that the phosphorus compounds are evenly distributed over the surface of the chrysotile fibres (within the resolution of the Cameca ion microscope) XPS and FTIR-PAS were used to monitor the conversion of the adsorbed POCl3 to a proposed polyphosphate coating. The formation of the polyphosphate coating occurs during the heating of the POCl3-treated chrysotile fibres to 300°C for 2 h. The resulting material is known as chrysophosphate. This study relates to the use of chemical coating to reduce the carcinogenic behaviour of chrysotile asbestos fibres.
