| Abstract: | HG-AFS was applied to the simultaneous determination of mercury in Euonymus fortunei.Effects of acidity and concentration of KBH4 solution on the hydride forming reaction,suitable conditions for the acid digestion of sample and the working condition of the instrument were studied and optimized.Detection limits(3S)of the method was 0.012 ng/mL,and recovery was 89.3%;the values of RSD was 2.39%.This method is sensitive and accurate and has been applied for the determination mercury in Euonymus fortunei with satisfactory results. |
