| Abstract: | The article introduces the method of cold vapour atomic absorption for determination of trace mercury in geochemical samples.In the research,a new generator of mercury vapour has been employed.Also,the effect of air bubble has been studied.The linear range of the concentration covers from 0.2ng/mL to 12ng/mL and the recovery of method is between 97% and 106%.The relative standard deviation is 3.6% and the correlation coefficient is 0.9997.The experimental results have shown this method is simple,rapid and accurate. |
