| Abstract |
The present work describes an improved method for the determination of total and organic mercury by decreasing analysis time (use of a dual circuit), sample size, and handling procedures and eliminating the need for a clean room condition while maintaining the detection limit below the parts per trillion (pptr) level. Total mercury was analyzed after reduction by a one-stage gold amalgamation before transfer to an atomic fluorescence spectrometer. Organic mercury was first derivatized using sodium tetraethylborate and then trapped onto a graphitized carbon trap before transfer to an isothermally controlled gas chromatography (GC) column coupled to a cold vapor atomic fluorescence spectrometer. The outlined analytical protocol permits a semiautomation of both inorganic and organic mercury analyses. |
