Description:
Sampling and analytical procedures used to determine total mercury content in crude oils were examined. Three analytical methods were compared with respect to accuracy, precision and detection limit. The combustion method and a commercial extraction method were found adequate to provide a good combination of sensitivity and accuracy while instrumental neutron activation analysis was found to suffer from interferences from elements other than mercury but typically in crude oil. Aliquot removal and processing steps were found to be important to accuracy and precision of the combustion method. Both elemental mercury and dimethylmercury were identified as volatile mercury compounds of one freshly sampled crude oil.
